Thanks Willik; I think the focus is good, but when greatly magnified, tracking inaccuracy [ star elongation in 5am to 11pm direction] becomes obvious, as does coma. [One day I'll find the money to get a coma corrector]. I think this
image was the beginning of my current tracking problems.

Nice one raymo liking the spiral arms and the Ha regions popping out. This is high on my list for those cold winter nights.

Thanks Dunk; I think this one needs longer subs, and lots of them.
