Progress, defects
This is a preliminary version of the Horsehead Nebula LRGB. So I shot this target two nights in a row, first with a red and luminance (mono brightness only) filters then the following night with green and blue filters. Celestron RASA 8 telescope (400mm focal length, f/2) on a Celestron CGEM2 EQ mount, QHY268M mono camera, Astronomik filters, PHD2 guiding, all controlled by NINA software. There are lots of problems with this shot, mostly from my cables causing ugly defects on the stars, and the cables moving between filters (and with the meridian flip). I am going to try to fix some of these problems with editing, but this is before I try.
