They are all good Mark, but I think I like the first one best because of the extra deep sky targets in the FOV.
Great stuff.
Carole
As good as you can get. I'm with Carole on the top image being my favourite. How often do you see diffuse nebulousity in a comet image? What a treat to get the comet with such a range of other celestial wonders. A lucky week.
Lovely trio Mark
Wow! Fantastic images! Such an amazing amount of detail!
