Polar Align Assistant and Non-GOTO. Can it be done? #33812
I am curious whether or not it is possible to use the PAA with a non-GOTO mount by manually rotating the RA by the approximate 30°. In other words will the calculations still work if the rotation is not perfectly consistent? . My goal is to Polar align a SW Star Adventurer with the routine.
I'm no expert, but my reasoning is that it should be possible since it is based on a form of triangulation, and that shouldn't require equidistant sample points. If this can be done, it would be good to have to option to untoggle automatic mode added back in do have the opportunity to move the mount before the next capture.
Thank you.

I support this feature request for support of the PAA tool for non-GOTO mounts.
Same usecase as OP: Star Adventurer

Did not realize this was removed. I had used it previously with star Adventurer before getting the AZ GTI - . So yes please revert to older way of having enabling auto mode.

I intend to do this from time to time as well. Perhaps not using a StarAdventurer but probably an iOptron SkyGuider Pro or Fornax LighTrack II but it boils down to the same thing, i.e. a non-Goto mount.

For guiding, do you use the internal guider or PHD2? If the internal guider, what Mount Device have you configured in the hardware profile? Telescope Simulator? Or something else?


Thanks, Wouter

I think when using manual rotation, three points would be needed instead of two; as the direction of rotation is unknown.

Good point Kengs. I do believe the PAA routine already uses 3 points.
