Astroart Forum

Hello,

I have two questions concerning script functions for filter wheels:

1. I use a Starlight Xpress wheel. When I move to a position using Wheel.Goto(n) the script doesn't wait until the position is reached. I have to configure a delay or program a Pause after the Goto. Does Astroart not get a feedback from the wheel when the position is really reached?

2. Is there a function like Wheel.GetPosition() to read the current position? As far as I know this can be read from some wheels.

Thanks!

Best regards,
Stefan

Hello,

1) Yes, a command "Pause(n)" may be necessary since the script does not wait for the wheel. This was made to allow two tasks at the same time, for example while the wheel is rotating you could start a dark frame or a telescope GOTO, saving 3-4 seconds on every image.

2) No. It could be added for ASCOM filter wheels in a future release of the CCD Interface.
