I've been playing with this data on and off for the best part of 2 years, never happy with the processing, but always thinking there was a decent image lurking in there somewhere. I've finally got something I think is worth posting.

Lovely shot. It looks very very nice.

Looks great Geoff.
very smooth. Colours look great, especially star colours.
Perhaps a bit more contrast and saturation, but then that's upto one's taste of course.

Cheers

Another fine image Geoff...you getting good at this

This object isn't imaged in LRGB very often, we are used to the higher contrast finer details supplied by narrowband filters, so this is actually very good

Thanks Alistair. Actually I had to push quite a lot to get where it's at. Any more and it started looking artificial. As Mike mentions below it's better as a narrowband object if one is going for contrast.

Terrific. Best RGB I've seen.

The star colours really make it. You've broken the Magenta barrier. Lovely.

A lovely, well cooked Prawn, Geoff! I agree wholeheartedly with the chorus of praise for the colours in this rendition.

Cheers,
Rick.

Thanks Mike, Trish and Rick. Star colours courtesy of the saturation boost in the PIxInsight CurvesTransformation. It really works very well.
