Thanks Andy
Appreciate your comments
Yes the Luminance version does give some full depth and detail of the Prawn
In the colour version I created a star mask so as not to include the stars during processing the main objects colour It’s a bad habit of mine as you don’t need too , Startools takes that into account and masks the majority of stars down to a few pixels ( only the teeny weeny faint stars get caught up the colour saturation )
Only when doing OSC Bi colour in Compose you have to mask your stars otherwise they end up with all sorts of unusual colours.
Unfortunately Star Masks do leave a few pixels of background around the perimeter.Some of it does get hidden after Noise Reduction ( in the form of smear )
I must admit though OSC narrowband under a full moon with the fainter nebulas like the Prawn is difficult to process your colour or even extract a suitable bi colour version
Ive had more success with the likes of M8 , M16 , M17 and a few others
Cheers
Martin
