I use a home made focuser and it works perfect with SGP (at least controls are perfect).
I can’t use the autofocus feature because SGP still consider wrong stars. I can’t achieve to make it detects correct stars. It still consider some dead column I have on my camera and It tries to calculate HFR on this bad columns.
So after the autofocus process SGP move the focuser to a bad position.
Here is a shot of what happen during the autofocus process.
I try to change some parameters with no success.
Thank you for your advice.
