Very nice. Colour looks fine to me. Yes focussing is easy, when I had a SB7 here for a night years ago, it was easy enough to focus, by selecting a star, it would only download that small area so would update so fast it was live video, so can focus in real time.
With the luminance R HA, is it equal weight to the R and HA or more to one or the other in the processing?
Whats the other project? I take it we here will be the first to see it here when its finshed
