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.

Super-ulrra-good. The colours in both the nebulosity and the background stars are very fine.

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 Andy. Of course the inspiration for the wider framing came from...

Great shot there Ben, you've gone quite deep and captured nice detail.

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!

Whoa Ben that's a ripper. Love the open cluster version and the colour is divine.

Stars look great, that's a high quality image.

Greg.

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 Suavi. It’s been quite different for me being in LRGB world so happy to get a result out of it :-)

An excellent trifid, Ben! Glad I could help in some small way. I actually prefer the slightly-wider field due to that lovely cluster in the corner.

A lovely rendition of this well known object.

Thanks Lee, Russ and Rodney. I like the wider field more now too, which was an attempt to copy Andy Campbell’s framing. M21 does make a nice pairing.

Nice image of this old favourite Ben. I like the colour balance and the background star fields a showing through well.

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.
