Well not bad at all Marc!
Nice everything, the collimation may be a problem, yes, but it's still very pleasing so imagine what it could look like with perfect colimation
As far as focusing goes, can you zoom in on a star in the FOV and just focus manually on it on the screen? If so, that is all I have ever done, no masks, no focusing routines nothing...? I seem to nail the focus every time with this very boring method?
