Looking good but red seems a bit bright ?

Very nice Fay!  I love the Helix.

Stars look sharp and round.  You've also brought out lots of faint wispiness.  Which scope did you use?

The only problem is that the Ha looks burnt out - is that something introduced during the processing or are the subs the same?

Mick, looking at other images, you can have what colour you want.

Mark, it is probably my processing, a new area for me, colour. ED80

I will reprocess, when I have got my brain together. I may have over done the ha processing

Fay, excellent images, but I do prefer the first one, as the nebulosity is a lot less harsh. :lol:

Great image Fay. Looks like an idea for a make-up ad!
