Scope Success, Meridian Flip Fail
The Horsehead and Flame Nebula, a stack of 11 shots processed in Photoshop. 1 of the frames was 10 minutes at ISO800, the rest were 20 minutes per frame, ISO400. Uncooled Nikon D810A on a Celestron CGEM2 mount, APT controlling the camera, ZWO guide camera with 60mm Sbvony scope for guiding with PHD2. The main scope is a Nikkor 600mm f/4 VR lens, shot wide open here. I had to keep adjusting the focus about every 40 minutes as the temp dropped, which is a pain! When I tried to do the meridian flip I messed it up and the scope lost its aligment, which for some reason I couldn't re-establish. I lost so much time I gave up for the night! Something I have to work on!
