Description

I am embarrassed to post this image as it is not very good at all, but it was my first attempt at DSO AP with this scope and mount.  I had guiding problems because, I thought the scope balance on the dec axis was a little off.  Looking this afternoon at the rig, it appears the problem was that level was off one bubble in each of the two indicators on the mount.  I've put that right now.  But this was at least a start and with luck and patience I'll get better with this rig.  At least I'm starting to learn how to use Astrophotography Tools much better than in the past and did use the Point Craft plate solving function etc. The focal length was 2209 mm using a 0.8x reducer with this 300mm native F9 modified Mak Cass scope.
