Hi everyone
I've around a 200 px error after a flip. It maybe related to this:
www.indilib.org/forum/ekos/3563-meridian...-did-not-happen.html
I have the astrometry indices installed and gotos via the ekos solver are very accurate. I think it maybe due to the tolerance of the solve (within x pixels say)
Question: where do I set the tolerance of the solver? Say, if the target is withing 30 px?

Any other pointers most gratefully received.
TIA,
Steve

You set that in the alignment module.

Hi
Unfortunately no mention of meridian limits:(
Haven't I already set it in capture by checking meridian flip?
TIA

The solver tolerance is set in arc seconds, not in pixels. By default it is set to 30" which could amount to 200 px with your telescope/camera combination. If you want the object to end up closer to the center of the FOV you'll need to decrease that tolerance. It is unrelated to meridian flip settings, which indeed are set in the capture module.

There is another option in the settings --> Reset Mount Model After Meridian Flip.

If you're using EQMod, this would be useful.
