DragScript Elements

The DragScript "language" is composed of blocks that are dragged from the list on the right side of the DragScript editor to the script being created or edited on the left.

Each category of element is organized in list that can be expanded or contracted by clicking the "+" or "-" next to the element category name:

E.g., if you click the + in front of Actions, the list expands like this:

As you can see in the case of Actions, there are further subcategories of actions, and clicking the + in front of one of them expands it again:

Here, the list of Setup actions is fully expanded and we see three choices that we can drag to the active script: Connect Setup, Connect Setup with Timeout, and Disconnect Setup

For the remainder of this page, we will describe the available DragScript elements. New elements are added periodically and will be documented in the release notes and here.

Press Sort button to listing all the categories and blocks in alphabetical order.

  - OK: Click to save your changes and close the window
  - Cancel: Click to discard your changes and close the window
Empty Voyager Temporary Folders: will remove all file from the temporary folders of Voyager (for example the FIT folder where is the temporary Shot for platesolving or pointing)

Session

Session actions run sequences to acquire images, flat frames, and shutdown ("Good Night") your system:

RoboTarget: Robotic Scheduler Available only in Voyager Advanced version
Sequence: Run a Sequence with options:

Configuration Panel:
- Click the folder icon to select the Sequence file to run. Create your Sequence files in Voyager's OnTheFly workspace
- Start/TimeSpan: Click one of the radio buttons to use that option to tell when to start and end the sequence. This is one way to have Voyager image this target until a specific time is reached, or an interval has elapsed. It is a good idea to specify an ending time here, or a minimum altitude in the Sequence definition or the Options field below, so Voyager will not continue trying to take images after the object has set
  - Start and End from Sequence: Use the start and end times specified in the sequence definition file. The start time comes from the On Start tab and the end time comes from the On End tab
  - Immediately Start and Finish After Interval: Start the sequence immediately and end it after the HH:MM:SS amount of time specified with the Time Span: counter fields
  - Start and End at Absolute Time: Voyager should wait until the specified Start: time and end the sequence at the specified End: time.
  - Immediately Start and End at Absolute Time: Start the sequence immediately and end it at the time specified in the counter fields
  - Immediately Start and Finish With Astronomical Night: Start the sequence immediately and finish it at Astronomical Night's end, offset +/- by the number of minutes set in the Offset: counter field
Calculated Time Span: Voyager will show how much time this sequence will take with the chosen Start/TimeSpan option if you choose Start and End at Absolute time. It is not possible to calculate this if you choose one of the "Immediately Start" options

Important Note! Enter time in 24 hour format using local time - or the time zone on the computer running Voyager. That's the time that will be used in doing these calculations. Midnight is 00:00:00. 10 pm local time is 22:00:00. 3 AM is 03:00:00.

Important Note! Note: If the Start: time is more than 12 hours in the future, Voyager will start the sequence, assuming that the start time has passed already in the current night. For example, if you specify a start time of 20:00:00 and it is now 20:15:00, Voyager will start the sequence

Important Note! If the End time is more than 12 hours in the future, Voyager will assume the End time has already passed for the night and end the sequence. For example, if a sequence has a Start time of 20:00:00 and an End time of 21:00:00 and the current time is 22:00:00, Voyager will end the sequence

Important Note! Times entered here will override any start or end times defined in the Sequence file. The times you define when you create the sequence are used for OnTheFly running of the Sequence, not for DragScript execution

Important Note! The Start and End times are checked at the beginning of running a sequence and the sequence exits with status OK if the current time is outside the Start and End time window

- Options: Check the boxes to select any of these options:
  - Overrides Target Coords J2000: If checked, the RA and DEC coordinates are used instead of those in the sequence file. RA coordinates are in HH MM SS and DEC coordinates are HH MM SS.sss
  - Overrides Target Name with this: If checked, the name entered in the field will be used as the target name, which is part of the file name
  - Force Dynamic Target Comet : if checked force the Sequence to use a Comet Dynamic Target type, you MUST select the Comet using the Comet Finder button near the check. If you check the flag and do not select a Comet the Sequence will generate an Error at starting. Target Name and Target key will be populated after the search and the overrides target name will be used with the name of the Dynamic Target. You can for sure change it.
  - Force Dynamic Target Asteroid : if checked force the Sequence to use an Asteroid Dynamic Target type, you MUST select the Asteroid using the Asteroid Finder button near the check. If you check the flag and do not select an Asteroid the Sequence will generate an Error at starting. Target Name and Target key will be populated after the search and the overrides target name will be used with the name of the Dynamic Target. You can for sure change it.
  - Override Dynamic Target Pointing Type : if checked and only if you are using a Dynamic Target (comet or asteroid) Voyager allow you to select when calculating the RA/DEC coordinates od the Dynamic Target. Default for a Dynamic Target is the Calculate RA/DEC only at Sequence Begin
    - Calculate RA/DEC Only at Sequence Begin : Voyager will calculate the RA/DEC of the Dynamic Target only whe the Sequence action will start and will use this RA/DEC for all duration of the Sequence action. If the Sequence will be restarted anothe day or some hours after or generally will be restarted VOyager will calculate again the RA/DEC coordinates. But not in the same Sequence run.
    - Calculate RA/DEC at Each Precise Goto : Voyager will calculate the RA/DEC of the Dynamic Target at each precise pointing goto inside the Sequence Run included at the begin of Sequence
    - Calculate RA/DEC Every X Seconds : Voyager will calculate the RA/DEC of the Dynamic Target at the beginning of the Sequence and each X seconds like edited in the dedicated field. if the X interval is expired and Voyager is in exposure camera mode, will wait the end of exposure to calculate the new coordinates. A realign goto will not be requested if the next flag is not checked.
      - And Realign Target : if checked Voyager will force a realign with a Precise pointing to the new RA/DEC of the Dynamic Target
      - Without Using Plate Solving : if checked Voyager will avoid the precise pointing with plate solving for the realign and will use a simple goto without solving
  - Override Angle Rotation of Target with PA of°: if checked , if in the sequence the rotator is managed, this flag force the Rotation Angle to the value selected. The other rotator settings in sequence will not be changed.
  - Finish Running Exposure in case of elapsed time for Sequence Execution: If checked, an exposure in progress will be allowed to finish if it starts before the sequence end time but finishes after the sequence end time
  - Override Lower Altitude value under which Exit from Sequence: If checked, if the sequence target sets below the altitude given here, the sequence will end. This value will override the minimum altitude value chosen in the sequence file
  - Override Higher Altitude value above which Exit from Sequence: If checked, if the sequence target rises above the altitude given here, the sequence will end. This value will override the maximum altitude value chosen in the sequence file
  - Override Lower HourAngle value under which Exit from Sequence: If checked, if the sequence target HourAngle are lower the value given here, the sequence will end. This value will override the Lower HourAngle value chosen in the sequence file
  - Override Higher HourAngle value over which Exit from Sequence: If checked, if the sequence target HourAngle are higher the value given here, the sequence will end. This value will override the Higher HourAngle value chosen in the sequence file
  - Override Camera Cooling Temperature with Decimal Variable: if checked for colling temperature will be used the value inside the decimal variable selected in the drop-box combo box control
  - Override Lower Azimuth value under which Exit from Sequence: If checked, if the sequence target Azimuth are lower the value given here, the sequence will end. This value will override the Lower Azimuth value chosen in the sequence file
  - Override Higher Azimuth value over which Exit from Sequence: If checked, if the sequence target Azimuth are higher the value given here, the sequence will end. This value will override the Higher Azimuth value chosen in the sequence file
  - Use External Interval Angle: if each the azimuth constraints will be cheched you can decide with this flag to use external angle instead of internal angle between before and after azimuth. Example if you choose 70° before and 150° after with out external flag this mean sequence run if angle is between 70 and 150°, if you chec it and invert to external sequence will be terminate if azimuth is between 70 and 150°
- Default: Click this button to populate this window with the default options
- OK: Click to save your changes and close the window
- Cancel: Click to discard your changes and close the window
- Override FILE PATTERN: flag this chheckbox to activate sub foldering and file naming with File Pattern method, insert in the big text field near the flag the string to override of the file pattern to use instead of the one configured in the File Pattern Manager. This will affect only the actual sequence and do not change the main File Patterm Manager configuration. This is for example mandatory in case of join of the OpenSkyGems network and sharing of the observatory setup.
Research & Survey: Run a Research & Survey sequence with options

Configuration Panel:
- Click the folder icon to select the Research & Survey sequence file to run. Create your sequence files in Voyager's Research & Survey workspace
- TYPO: Star/TimeSpan should be Start/TimeSpan
- Start/TimeSpan: Click one of the radio buttons to use that option to tell when to start and end the Research & Survey sequence. This is one way to have Voyager image this target until a specific time is reached, or an interval has elapsed. It is a good idea to specify an ending time here, or a minimum altitude in the Research & Survey sequence definition or the Options field below, so Voyager will not continue trying to take images after the object has set
  - Immediately Start and Finish After Interval: Start the sequence immediately and end it after the HH:MM:SS amount of time specified with the Time Span: counter fields

Sync Warmup: Send the CCD cooler a warmup command and wait until it finishes
Async Warmup: Send the CCD cooler a warmup command and continue execution without waiting for it to finish
Parking: Park the mount as specified in Mount Setup

Plate Solving

Plate Solving actions perform a plate solving action as defined in the Plate Solving setup of the active profile:

Plate Solving : Perform a plate solve action at the current scope location using the Plate Solve software defined in the Plate Solving setup of the active profile. Mount will not be synched
Plate Solving with Mount Sync: Perform a plate solve action at the current scope location using the Plate Solve software defined in the Plate Solving setup of the active profile. Send a Sync command to the mount unless you have chosen to not send a Sync command to your mount in Mount Setup. You may lost pointing model if you have one and your driver not allow additional and external sync

Blind Solving

Blind Solving actions perform a plate solving action as defined in the Plate Solving setup of the active profile:

Blind Solving with Mount Sync: Perform a blind solve action at the current scope location using the Plate Solve software defined in the Plate Solving setup of the active profile. Send a Sync command to the mount unless you have chosen to not send a Sync command to your mount in Mount Setup. You may lost pointing model if you have one and your driver not allow additional and external sync

WEB Solving

Plate Solving actions perform a plate solving action as defined in the Plate Solving setup of the active profile:

Web Solving with Sync: Perform a web blind solve action at the current scope location using the nova.astrometry.net site. An active Internet connection is required. Send a Sync command to the mount unless you have chosen to not send a Sync command to your mount in Mount Setup
- - Timeout: Specify the number of minutes Voyager should wait after initiating the Web Solve before timing out. Use an IF TIMEOUT decision action to define what to do if the web solve times out

Guiding

Guiding actions send commands to the guide software:

Calibrate Guide: Command the guide software to perform a calibration action. It is recommended to include a Calibrate Guide action at the start of your sequence unless you are sure that your guider is calibrated from a previous session. Double click to bring up the configuration window:

Time: Exposure time for Calibration exposures by the guiding software
Binning: Binning level for Calibration exposures by the guiding software
Use RoboGuide Star Selection: If selected, use Voyager's RoboGuide process to choose a guide star for the Calibration action. This is mandatory at this time since some guiding software cannot select a guide star.
Default: Use the default settings
OK: Save changes and close the window
Cancel: Discard changes and close the window

Acquiring Guide Star: Commands the guiding software to select a guide star. Double click to bring up the configuration window:

Time: Exposure time for guide star acquisition exposures by the guiding software
Binning: Binning level for guide star acquisition exposures by the guiding software
Use RoboGuide Star Selection: If selected, use Voyager's RoboGuide process to choose a guide star. This is mandatory at this time since some guiding software cannot select a guide star.
Default: Use the default settings
OK: Save changes and close the window
Cancel: Discard changes and close the window

Guide Start: Commands the guiding software to begin guiding. Double click to bring up the configuration window:

Time: Exposure time for guiding exposures by the guiding software
Binning: Binning level for guiding exposures by the guiding software
Use RoboGuide Star Selection: If selected, use Voyager's RoboGuide process to choose a guide star. This is mandatory at this time since some guiding software cannot select a guide star.
Default: Use the default settings
OK: Save changes and close the window
Cancel: Discard changes and close the window

Guide Stop: Command the guiding software to stop guiding

Guide Dithering: Command the guiding software to perform a dithering action. Dithering is used to move the mount a tiny random amount in a random direction - usually only a couple of pixels. This prevents hot or cold pixels in your sensor from showing up in the same position in all of your images, making it easier to remove hot or cold pixels when stacking your images. Double click to bring up the configuration window:

Max Pixel: Specify the maximum number of pixels that a dithering operation can move the mount
Default: Use the default settings
OK: Save changes and close the window
Cancel: Discard changes and close the window

Unguided Dithering: Perform a dithering action directly, vs. Guide Dithering which sends a dithering command to the guide software. Dithering is used to move the mount a tiny random amount in a random direction - usually only a couple of pixels. This prevents hot or cold pixels in your sensor from showing up in the same position in all of your images, making it easier to remove hot or cold pixels when stacking your images.

Max Pixel: Specify the maximum number of pixels that a dithering operation can move the mount
From Actual Position: This is the safest and default choice - it sends a command to move the mount up to the specified number of pixels from the current position. This should be a small movement, as the recommended number of pixels to dither is 3
From Last Goto Action Position: Send a command to move the mount a random number of pixels up to Max Pixel in a random direction relative to the position of the last Goto action. This should only be used following a successful Goto action in your DragScript. You can damage your mount if you use this without a successful Goto action preceding it.
From Last Precision Pointing Action Position: Send a command to move the mount a random number of pixels up to Max Pixel in a random direction relative to the position of the last Precision Pointing action. This should only be used following a successful Precision Pointing action in your DragScript. You can damage your mount if you use this without a successful Precision Pointing action preceding it.
Use Actual Position on Empty/Fail condition: If checked, if the position reported by the Last Goto Action or Last Precision Pointing Action is empty, or if the Last Goto Action or Last Precision Pointing Action ended with an error, use the Actual Position of the mount as the starting point for dithering. In other words, don't attempt to dither based on the Last Goto action position or the Last Precision Pointing action position if either of those positions is empty, as this would send a command to the mount that could cause a pier crash and/or damage to your equipment. Highly recommend leaving this checked.
Default: Use the default settings
OK: Save changes and close the window
Cancel: Discard changes and close the window

Mount

Mount actions send commands to the mount defined in the Mount setup of the active profile:

Stop Tracking: Command the mount to stop tracking
Start Tracking: Command the mount to start tracking
Parking: Command the mount to slew to the Park position
Unparking: Command the mount to Unpark
Sync on Park: Command the mount to save the current position as the Park position

Goto RA/DEC: Command the mount to move to the specified RA and DEC coordinates (J2000)

RA J2000: Enter the RA coordinates in HH MM SS or HH MM SS.sss
DEC J2000: Enter the RA coordinates in DD MM SS or DD MM SS.sss
Default: Use the default settings: clears the RA and DEC fields
OK: Save changes and close the window
Cancel: Discard changes and close the window

Goto ALT/AZ: Command the mount to move to the specified Altitude and Azimuth coordinates

ALT: Enter the Altitude coordinates in DD MM SS or DD MM SS.sss
AZ: Enter the Azimuth coordinates in DD MM SS or DD MM SS.sss
Force Use of Normal RA/DEC Slew With Conversion: If checked, convert the requested ALT and AZ values to RA and DEC values and send a goto RA/DEC command to the mount
Default: Use the default settings: clears the AZ and ALT fields
OK: Save changes and close the window
Cancel: Discard changes and close the window

Goto Near Zenith: Command the mount to move to a point close to the current Zenith (directly overhead).

Important Note! Goto Near Zenith followed by a Blind Solving with Sync action is a good way to initialize your mount's pointing model at the start of a session. It is only a single point, but if your mount is accurately polar aligned, doing this before the first Precise Pointing operation may helps the Precise Pointing to succeed

Goto By Name: Command the mount to move to an object by name with an optional RA and DEC offset. This action requires Voyager to be connected to the Planetarium software defined in the current profile. The Object Name must match a name that can be successfully searched in the connected Planetarium software.

Object Name: Name of the object to goto. Must be a name that can be successfully searched in the connected Planetarium software
Offset RA (optional): An optional +/- offset in HH MM SS or HH MM SS.sss to be added or subtracted from the RA coordinates returned by the Planetarium software

Goto By Offset: Command the mount to move from actual position by an RA and DEC offset.

Offset RA : +/- offset in HH MM SS or HH MM SS.sss to be added or subtracted from the actual RA coordinates
Offset DEC : +/- offset in DD MM SS or DD MM SS.sss to be added or subtracted from the actual DEC coordinates

Precise Pointing: Command the mount to perform a precise pointing operation to the specified RA/DEC coordinates - slew to the object, plate solve to get actual coordinates, re-slew to correct pointing error:

RA J2000: Enter the RA coordinates in HH MM SS or HH MM SS.sss
DEC J2000: Enter the DEC coordinates in DD MM SS or DD MM SS.sss
Max Error using Multiple of Profile Error by: If selected, multiply the maximum allowed pointing error by the number specified in the counter field. E.g., if the Precision Pointing Max Allowed Error specified in Mount Setup is 50 arc-seconds, a value of 2 in the counter field here would change the maximum pointing error to 100 arc-seconds. Precise pointing returns an OK (success) result when the error is less than the Max Error.
Max Error is: If selected, use the value specified in the counter field as the maximum pointing error in arc-seconds. Precise pointing returns an OK (success) result when the error is less than the Max Error.
RoboClip: open RoboClip manager windowd and allow to select a target,
Default: Use the default settings
OK: Save changes and close the window
Cancel: Discard changes and close the window

Precise Pointing by Name: Command the mount to perform a precise pointing operation to the specified named object - slew to the object, plate solve to get actual coordinates, re-slew to correct pointing error. This action requires Voyager to be connected to the Planetarium software defined in the current profile. The Object Name must match a name that can be successfully searched in the connected Planetarium software.

- Object Name: Name of the object to goto. Must be a name that can be successfully searched in the connected Planetarium software
- Offset RA (optional): An optional +/- offset in HH MM SS or HH MM SS.sss to be added or subtracted from the RA coordinates returned by the Planetarium software

Precise pointing returns an OK (success) result when the error is less than the Max Error.
- Max Error is: If selected, use the value specified in the counter field as the maximum pointing error in arc-seconds. Precise pointing returns an OK (success) result when the error is less than the Max Error.
- Default: Use the default settings
- OK: Save changes and close the window
- Cancel: Discard changes and close the window

Precise Pointing Mount & Rotator: Command the mount to perform a precise pointing operation to the specified named object - slew to the object, plate solve to get actual coordinates, re-slew to correct pointing error, rotating the rotator and align to the requested PA within the specified tollerance.

- RA J2000: Enter the RA coordinates in HH MM SS or HH MM SS.sss
- DEC J2000: Enter the DEC coordinates in DD MM SS or DD MM SS.sss
- Max Error using Multiple of Profile Error by: If selected, multiply the maximum allowed pointing error by the number specified in the counter field.

Precise pointing returns an OK (success) result when the error is less than the Max Error.
- Max Error is: If selected, use the value specified in the counter field as the maximum pointing error in arc-seconds. Precise pointing returns an OK (success) result when the error is less than the Max Error.
- Rotation Angle: an arbitrary angle that can be a Rotator PA or Sky PA, depends on following setting.
- Rotation Type: define if the rotation angle is the rotator angle (rotator PA) reported from the driver (and with offset if asked to Voyager in Sync) or the Sky angle (Sky PA) chosen with web dashboard VirtualFOV or planetarium or another system. If you select Sky PA Voyager will use the Plate solve PA result to rotate the rotator to the right angle. If you select the Rotator PA Voyager will just rotating rotator using drive angle at desidered value, no correction using the plate solved PA will be done
- PA Tollerance +/-: if the PA of rotator is inside the interval given the position will be declared ok and rotator will not be rotate.
- Rotator & Meridian Flip: "Mantain the Same Image Orientation After the Meridian" if checked force Voyager to shot the target with same orientation in the images taken before anf after meridian. In this case if you have chosen Rotator PA like Rotation type the rotator will be flipped if the mount is after the meridian, if you chosen Sky PA the PA will retained also after the meridian triggering a rotator flip.Use this flag is useful also to use always the same guide star in case of use of OAG or system with high focal lenght.

Important Note! Dragscript editor doesn’t have access to profile configuration, for this reason you dont find setting about readout mode and speed in exposure block. Exposure block use auto mode of readout mode and default speed mode. This mean chooses are based on shot type and binning. It retrieve automatically the correct values you set up on Voyager camera setting tab.

Important Note! Filter labels are shown in this dialog if the DragScript editor is opened from Voyager and filter labels are defined in the current profile. Otherwise only filter indexes are shown. The first filter is index zero (0)

Important Note! If you check the use variable flag the exposure time used for the exposure will be added to the name of FIT file

AutoFocus

These DragScript commands perform Voyager's autofocus operations:

Important Note! If you have a flat device that can open and close, don't forget to issue an Open Flat Device command in your DragScript before taking exposures including plate solving and autofocus!

Script

The Script action can run an external script or program:

File Program/Script: Click the folder icon to select the program or script to run
Arguments: Command line arguments to be passed to the program or script when invoking it
Wait For Program/Script: If checked, wait for the program or script to return before continuing (synchronous execution)
On Timeout Kill Program/Script: If checked, and the "Wait for Program/Script" option is checked, and the "Wait / Timeout" time period has elapsed, terminate the external program or script
Return OK to DragScript Engine only if Script return this: If checked, the script or program must return the value specified in the text field in order for this action to be considered a success and return OK
Save External Script output to this DragScript String: If checked, store the value that the external script or program returns in STDOUT to the DragScript string variable chosen from the drop-down list
Save External Script output to this DragScript Decimal: If checked, store the value that the external script or program returns in STDOUT to the DragScript decimal number variable chosen from the drop-down list
Default: Use the default settings
OK: Save changes and close the window
Cancel: Discard changes and close the window

Important Note! Voyager will only terminate the specified program or script when the timeout period expires. If the called program calls other programs, they will not be terminated by Voyager

Important Note! If the value returned from STDOUT is stored in a DragScript decimal number, be sure that the number returned uses a period as the decimal point separator

Example of Use

In this example, we call a Python script located in the directory d:\VScheduler\Scheduler.py, and wait up to 10 seconds for the script to complete.

The Python script writes a value to STDOUT with this code:

import sys

sys.stdout.write('RUN')

sys.stdout.flush()

We store that value in the SchedulerResult DragScript string variable. We can then make decisions in the DragScript using the DO IF STRING VALUE statement.

Timing

Timing actions inform DragScript to wait before performing an action. You can wait for a time interval, an absolute time to be reached, astronomical night with an offset, or for an object to reach a desired altitude:

Wait Time: Wait for a specified time to arrive or to elapse

Interval/Time: Enter a time in HH MM SS.
Wait Type: Chose Absolute or Relative
- Absolute: Wait until this absolute time is reached. If the time specified is more than 12 hours in the future, Voyager will assume this time has passed and will not wait. For example, if the specified time is 20:00:00 and this action is executed at 20:15:00, Voyager will not wait because that would cause a wait until tomorrow night, which is probably not what you intended
- Relative: Wait for this amount of time to elapse
OK: Save changes and close the window
Cancel: Discard changes and close the window

Wait Altitude: Wait until the object at the given RA and DEC coordinates reaches the specified altitude, either rising or setting:

RA Target J2000: RA coordinates of the object you want to reach the Reference Altitude in HH MM SS or HH MM SS.sss
DEC Target J2000: DEC coordinates of the object you want to reach the Reference Altitude in DD MM SS or DD MM SS.sss
Reference Altitude: Altitude to reach in degrees
Exit Wait if Actual Altitude GREATER than or EQUAL (>=) to reference: Wait until the target rises above the reference altitude
Exit Wait if Actual Altitude LOWER than or EQUAL (>=) to reference: Wait until the target sets below the reference altitude
Wait Altitude until absolute time: The Wait Altitude operation will terminate when this time is reached, whether or not the target has reached the reference altitude. This is usually done to end the wait with morning light
Activate Antiglitch Altitude Reading System: set the flag if you want to activate an AntiGlitch system to avoid glitchy readings of values from mount drivers that have undeclared bugs (3 continuous readings are done to get the OK). Sometime happens in buggy drivers a single reading is damaged and trigger the OK to wait altitude status. I fyou have this problem activate the flag but report the problem to the mount driver developer.
RoboClip: load RA and DEC from RoboClip catalog
Coords From Sequence: load RA and DEC from a sequence file
Default: Use the default settings
OK: Save changes and close the window
Cancel: Discard changes and close the window

Wait Astronomical/Nautical/Civil Night: Wait until astronomical/nautical/civil night, with an optional offset:

Get Latitude and Longitude from Mount: Retrieve the current latitude and longitude from the connected mount, which must support this command. This location is used, along with the current date, to determine the time that night begins
Use the Latitude and Longitude indicated below: Specify your current latitude and longitude in the fields below. This location is used, along with the current date, to determine the time that night begins
Offset: Time in HH MM SS
- Offset Before: If selected, exit the wait this amount of time before night
- Offset After: If selected, exit the wait this amount of time after night
Exit with ERROR if Wait Time is Greater than: if this option is flag the DragScript will exit with Error if the time wait for the begin of the next astronomical night is greater than the value in hour expressed in the numeric edit. Useful if you want to detect that the actual night is already finished and the dragscript can exit otherwise without this flag the next astrnomical night will be waited
Default: Use the default settings
OK: Save changes and close the window
Cancel: Discard changes and close the window
Wait Dusk

Get Latitude and Longitude from Mount: Retrieve the current latitude and longitude from the connected mount, which must support this command. This location is used, along with the current date, to determine the time that dusk begins
Use the Latitude and Longitude indicated below: Specify your current latitude and longitude in the fields below. This location is used, along with the current date, to determine the time that dusk begins
Offset: Time in HH MM SS
- Offset Before: If selected, exit the wait this amount of time before dusk
- Offset After: If selected, exit the wait this amount of time after dusk
Save Time to Event (minutes) in Decimal: Save the computed time until Dusk in a decimal variable. See the DragScript example below for one way to use this.
Default: Use the default settings
OK: Save changes and close the window
Cancel: Discard changes and close the window

You can configure the time at which dusk begins in the SkyFlat section of Flat Device Setup.

Important Note! If dusk (plus or minus the offset if one is specified) has already passed, Wait Dusk returns OK if it has been less than 12 hours since dusk, else it returns ERROR if has been more than 12 hours

Wait Dawn

Get Latitude and Longitude from Mount: Retrieve the current latitude and longitude from the connected mount, which must support this command. This location is used, along with the current date, to determine the time that dawn begins
Use the Latitude and Longitude indicated below: Specify your current latitude and longitude in the fields below. This location is used, along with the current date, to determine the time that dawn begins
Offset: Time in HH MM SS
- Offset Before: If selected, exit the wait this amount of time before dawn
- Offset After: If selected, exit the wait this amount of time after dawn
Save Time to Event (minutes) in Decimal: Save the computed time until dawn in a decimal variable. See the DragScript example below for one way to use this.
Default: Use the default settings
OK: Save changes and close the window
Cancel: Discard changes and close the window

You can configure the time at which dawn begins in the SkyFlat section of Flat Device Setup.

Important Note! If dawn (plus or minus the offset if one is specified) has already passed, Wait Dawn returns OK if it has been less than 12 hours, else ERROR if more than 12 hours

Wait Safe: Wait Safe Condition wait the safe condition before allow dragscript to execute net instruction. During the wait the events like Emergency Exit and Emergency suspend will be disabled and not managed. Just to remember you emergency events can coming from Viking I/O, Safe Monitor control, Weather Condition control. Like said this action will forcing event disable until exit for timeout or for safe. So be sure to have the observatory on the right configuration to avoid weather damage (closed and all parked). This action allow Voyager to run forever DragScript in case of no emergency exit. Can wait a time or an interval or the presence of astronomical/nautical/civil night, with an optional offset. Usually this is the first action in a script, its a good thing to put the Start node in Event disabled mode when you are manage the events in your DragScript. Also remember that the event at exit of this action will be restored to the original status, if they are disabled they will be leave disable or viceversa. We suggest also generally in dragscript to disable events during an atomic tasks like the opening observatory and connect setup to avoid interruption not really needed with impredictable results. If the action finish for wait will produce a status of TIMEOUT to the DragScript, if the action finish for one of the exit options will produce a status of ERROR to the DragScript, if the action found a SAFE status inside the wait option will produce a status of OK to the DragScript. You can decide if repeat the the action in a never ending loop (if you use night this mean to wait for the next night if you not check the exit ERROR options) or simple end the DragScript if you start DragScript night by Night. Rember that an Emergency Exit in any case will exit the DragScript.

Important Note! Wait SAFE Cannot be used inside the Event Manager (Exit, Suspend, Resume)

Wait SAFE until finish Night: this option wait SAFE status until on eof specified kind of Nights is finished
- Get Latitude and Longitude from Mount: Retrieve the current latitude and longitude from the connected mount, which must support this command. This location is used, along with the current date, to determine the time that astronomical night begins and end
- Use the Latitude and Longitude indicated below: Specify your current latitude and longitude in the fields below. This location is used, along with the current date, to determine the time that astronomical night begins and end
- Night TYPE: the night to wait between Astronomical (Astrophotographers dark night -18° sun) , Nautical (-12° sun), Civil (-6° sun)
- Offset: Time in HH MM SS
  - Offset Before: If selected, exit the wait this amount of time before astronomical night
  - Offset After: If selected, exit the wait this amount of time after astronomical night
Wait SAFE until absolute time: this option wait SAFE status until the absolute time you put inside the hh mm ss field
Wait SAFE for a time interval of: this option wait SAFE status until the amount of time in the interval will be elapsed
EXIT Options: with this options you can decide to exit with ERROR it the conditions inside is true
- Exit with ERROR if the Astronomical Night has ended less than: if this option is flag the DragScript will exit with Error if the astronomical night is ended by the time in hh field. This work and be active only if you use Wais SAFE with astronomical night. This flag enabled prevento to wait for the next night if the night is finished and you want to shutdown all without wait the next night.
- Exit with ERROR if Wait Time is greater than: if this option is flag the DragScript will exit with EORR if the time to wait is greater than the value in the hh field. This option is active only if you choose the Wait SAFE until absolute time. Useful if you dont wait over a certain time span.
EVENT CHECK options: with this option you can decide to remove from processing status of SAFE some kind of events that will be ignored (event in any case are disable during the wait safe action)
- Check Emergency Exit Status in SAFE status calculation: if unchecked the condition that throw an Emergency Status will be ignored in calculation of SAFE Staus . ATTENTION !! this is a way really dangerous for your setup .. use only if you want to wait safe in particular condition , particular timing and for particular tasks
- Check Emergency SUSPEND Status in SAFE status calculation: if unchecked the condition that throw an Emergency Status will be ignored in calculation of SAFE Staus . ATTENTION !! this could be a way really dangerous for your setup .. use only if you want to wait safe in particular condition , particular timing and for particular tasks.
LIGHT CONDITIONS options: with this option you can decide to remove from processing status of SAFE the LIGHT Conditions status
- Remove Weather LIGHT Conditions Status From Calculation of All Emergency Status: if unchecked the LIGHT conditions from Weather system will be not used to calculate the SAFE Status. Usefull if you want to open the dome with the light approaching the night time and do skyflat. For the Dawn flat you can decide to disable the LIGHT event using dedicated block
MOON PHASE Options (Only for ADVANCED and FULL License Voyager versions): useful to ignore Safe status if the Moon Phase is over certains value
- Unsafe if Moon Phase equal or greater than: if checked Voyager will check the Moon Phase and if the value is equal or greater than the one indicated will return Unsafe to Emergency Events system
Default: Use the default settings
OK: Save changes and close the window
Cancel: Discard changes and close the window

Using the Time to Event Value in a DragScript

Here's an example of using the Save Time to Event (minutes) value in a DragScript.

The basic idea is that you can decide whether or not to execute any actions based on how many minutes there are until or after dawn or dusk.

The decimal variable "Minutes Before Event" is initialized to 0.

The Wait Dawn: Data from connected Setup - Offset (Before) 00:15:00 [hh:mm:ss]>>Minutes Before Event action waits until 15 minutes before dawn, and then puts the value 15 into the variable Minutes Before Event

The DO IF DECIMAL VALUE block will execute if the Minutes Before Event variable is between 0 and 15. If not, control passes to the End block.

The Goto Block: DAWN FLAT statement sends control back to that block, and the minutes before or after dawn are computed again and stored in the Minutes Before Event variable.

If it is after dawn when the Wait Dawn action runs, the value stored in Minutes Before Event will be negative, and the DO IF DECIMAL VALUE statement will not run.

Guide to obtain API ID and Chat ID :

Download the Telegram APP on your mobile phone and register
Open a chat with @BotFather and type /newbot to create a new private bot
You will be asked for a friendly name - choose whatever you like, e.g. VoyagerMessages
You will be given an "API Token" - save this somewhere - it is what you will enter as the API ID in your DragScript action, as shown above
In your browser (can be on a desktop, doesn't have to be on your phone) open the link https://api.telegram.org/botYOUR-TOKEN/getUpdates replacing YOUR-TOKEN with the API Token
You will get a short message that starts with {"ok":true. It won't have the Chat ID yet - this is OK
Go back to Telegram and find the last message from @BotFather that starts with "Congratulations on your new bot. You will find it at ..." Click on that link and a new message room will open in Telegram, talking to your bot
Type at least one message - a simple "hello" will do
Go back to the browser page you opened in step 5 and hit reload - now you should see more characters including a long number after "from":{"id": That number is the Chat ID, which you use in your DragScript Send Telegram action as shown above
If you don't see the Chat ID, try sending a couple more messages to your bot in Telegram and then quickly reload your browser until you get the ID
That's it - you can now use the API ID and Chat ID to send Telegram messages from your DragScript
