Hi Tony
The blue gave the most detail.
Re trap and other stars.
I cheat here a little.
Usually there is little to see with stars in this usually blown out region.
I use first the burn tool in PS sample the darkest part of the blown out region and use that tool to make that area darker without affecting other parts of the image...most of the stars are bearly visable even after merging in the best short exposure core that I can produce...so then get the burn tool make it the same diameter as the faint stars and "hit" them a few times until they are nice and bright...I think such a system would be great for giving a few key stars colour if lacking.
So a few stars treated like that should help when,if ever, I get decent colour data.
I am doing this again from scratch right now with 663 images that I spent a long time reviewing to find the most suitable...U do have some colour so I will start building and see what they look like after stacking and processing.
This narrow band is really something else..I am only doing 10% of the work and yet it is taking all my time..
I worked out you need approx 28 groups of captures when you add up lights, darks, flats and dark flats...
Thanks for your kind words.
Alex
