Thanks Steve. I liked the FOV but was a bit unsure if I was over the top on the colour. This is the "toned down" version!.

Thanks Rick. Yes the scope seemed to pick up some interesting details.

Firstly the camera - the 16803 has 100,000 electron full well so it can capture some bright stuff without getting overwhelmed. Secondly I used the shadows/highlights too to reduce the highlights and 3rdly the AP Honders scope is really well baffled so I think it helped a lot there too. I actually had a ring reflection artefact on the LRGBs. I took a 2nd run and moved the scene a tad to reduce it. Then when I processed them together this acted like a dither and magically the ring reflection artefact disappeared. I was nicely surprised there. When I first saw the reflections I started wondering how I was going to get rid of them so that worked out accidentally well. So if you get nasty reflections try a large dither (like 10% movement of the frame)

Thanks Mike. Yes that combo works really well on these very wide areas and they are an excellent matchup.

Greg.
