In my case I’m doing long (2500mm+) FL Galaxy and cluster imaging and I usually need to switch focus off too as Autofocus picks the galactic core as its preferred focus target often enough that it’s become a problem. I hadn’t thought about offering up a sacrificial star, I had been contemplating asking for an “autofocus exclusion area” E.g.: a square or eclipse in the middle of the frame that you can specify NOT to use for autofocus

The other idea of course is Full Frame focusing, but I’ve not had much luck getting that working, could be user error.


You do know about the Annulus settings in the focuser, where you can set a size for the inner ignore area ?
