Description

This is another attempt to learn Sequence Generator Pro. I got an automated meridian flip and a complete run on this attempt, but I’m still struggling with focusing. I have yet to be successful with autofocus, which may not really be possible with my gear. At any rate, this image suffered a bit from focusing issues. All things considered, it’s a much better image than my previous attempt at this target, so I’ll take it. I ought to try this again with a focal reducer to widen the field of view a bit.

The B revision adds Astronomy Tools local contrast enhancement.
