Nothing special but glad I finally have M20 in LRGB and that my flats mostly worked! Small steps....
Did a close up and a framing with M21 following the amazing examples I've seen about the place.

Thanks Marc and Mike :-) I tried out a new PixInsight stretching routine as suggested to me by the amazing Lee Borsboom: a slight histogram stretch followed by an ArcSinh stretch to keep some colour intensity, which seemed very effective when adding the Luminance.
Thanks Colin. I was happy to get what I could but makes me excited about the possibilities of city based LRGB :-) Of course many many fine examples here of that but had to see for myself!
That’s very kind of you to say Greg. With so many things in flux (back spacing from the CC, tilt, flats that work, LP, wind, blah blah) I feel rather lucky to get anything with all the constant juggling. I guess that’s backyard AP though, and it is still bloody good fun!
Thanks Paul :-) The back ground stars are rather intense! I was admiring Andy C’s image for almost the opposite reason but perhaps that is more to do with star size than intensity.
