Rotator Setup

Color Coding

Throughout the Setup workspace, Voyager uses color to indicate the following:

Black: A normal setting
Gold or Yellow: Use caution when changing as things may not work well or as expected
Red: Use extreme care when changing this setting - the wrong value can damage your equipment or the imaging session may fail

Rotator Setup Workspace

Click the Rotator button in the Setup workspace to display the Rotator Setup window:

Rotator Choice

Select your rotator from the drop-down list at the top of the Rotator Setup window:

The options are None for no rotator
ASCOM Rotator for a rotator controlled via an ASCOM driver.
RCOS TCC Rotator for RCOS hardware
Click the ASCOM button to choose the ASCOM driver for your rotator

Sync Management

For sync we talk about synchronize the position angle of the rotator to the Equator position angle (or the arbitray angle). Voyager can manage Rotator Sync based on the driver capabilities:

- (A) Driver without Sync (like ones with ASCOM Interface V2)

- (B) Driver with Sync (like ones with ASCOM Interface V3)

The value of offset for Sync can be managed using the Sync button in Rotator Command Widget in Voyager GUI column Command.

You will input manually the angle to sync.

If you have driver type (A) Voyager will calculate automatically for you the Offset and value will be stored in actual Voyager Profile. You might have more Voyager profiles with different offset if you sharing the same driver and rotator.

If you have driver type (B) ASCOM Driver will calculate automatically for you the Offset and value will be stored in ASCOM driver settings permanently. Value stored will be equal for all Voyager setup profiles in case of driver and rotator sharing.

Rotator Workaround

The Rotator Workaround panel of the Rotator Setup workspace contains a workaround for rotators that require a delay after finishing the move and before resuming exposures:

Wait Time After Rotator FInished Move: Check the box and enter the delay time in seconds if your rotator requires Voyager to delay the next action after the rotator move finishes. This can be helpful if your rotator returns from the "Move" command before it actually finishes the rotation, or if a delay is required after the move completes to allow vibrations to settle down. Some rotator drivers report rotation is finished before the rotator has actually stopped. This can cause elongated stars if the next exposure starts immediately
Reverse: activate the reverse calculation of rotation, useful if during Sky PA point the calculate angle not converge to the sky PA requested. This flag can be applied if your driver support the reverse ASCOM option. Changing to this flag need to disconnect and reconnect the setup in Voyager to apply the change.

Important Note! In case of Reverse do not use the ASCOM Driver flag but the flag in Voyager because this flag will override the ASCOM settings flag.

Optec Perseus Facility

This box allow you to select the ASCOM driver to manage the Optec Perseus system (multi camera selector):

RCOS Rotator

RCOS rotator driver is not a real ASCOM driver but a COM interface with same named methods and properties.

Please be sure to use the version 1.5.26 of RCOS Telescope Command Center to allow Voyager to connect and manage the rotator and focuser.

Press the ASCOM button to select the driver to use. You must have installed the Optec Persesus Driver.
