I love this target because the colours are so contrasting side by side. 134 x 5min L ultimate Filter + 144 x 5min Baader Fringe killer UV/IR. Asiair 533 MC Pro OSC with Svbony 102ED. I processed this in Pixinsight and polished off in Photoshop.

Very bright and cheerful Paul.

You got some nice background Ha which is a new look for these images that older CCD images did not pick up.

Very sharp and detailed and a very pleasing image.

Greg.

Indeed, very colourful, but, back in the Jurassic , those "old" CCD images did detect that extended Ha (attached circa 2015, Ha only CCD data)

Peter - by the look of that monochrome image any nebulosity in the final image (colour) would be... well.. dim at best. see attached a mono of my cmos version as an example

I take your point, but I'd only captured an hour's worth of Ha data....it never occurred to me to go much deeper on such a bright object...so indeed, well done with your rendition.

Your images are all legendary regardless of how much Ha is in the back ground
