Hi Raymo
The irony for me is I would have be one of the first few buying a computer and I even learnt a little "basic" the programing language but some how drifted away and have not had a computer for a decade up to 18 months ago.
Anyways keep going as you really are producing great work.
As to polar align...
I would get the scope in line with the polar axis switch off the mount and take a long exposure to get star arcs...such that you could see the center of the circle in your capture and then move the polar axis so the center of the star circle iwas in the middle of the photo...it can take a while but if you have the scope and the polar axis in line you can get rather decent polar alignment. With my mounts I would line up an object in the distance in the day and make sure the scope saw what the polar scope viewed...anyways you may get a method from my approach.
I now use pole master...but last time out I could not find sigma oct for some reason and so took star circles thru the polemaster camera to get sigma oct on screen...and strangly☺ I ended up cclose to a decent PA before I went through the polemaster proceedure.
