just the stacked and calibrated images, no processing other than flats/darks/biases. It makes it easier all round.
i'll see what i can do.
best wishes

Hello, I am new to this group, and am new to narrowband imaging. In fact, I'm working on my first narrowband image, a bi-color image of NGC6888 (Crescent Nebula). I feel as though I have good Ha and OIII data with round stars and a sharp image. However, I am struggling with putting them together into a color image. It seems as though when combining the images the color gets completely washed out. I've tried mixing different arrangements, all with the same result.
Any advice as to how to combine the images would be most appreciated. Perhaps the best thing would be for someone to take the raw Ha and OIII images and see what they can do with it, then tell me what they did. I'd be glad to send the images to someone willing to do that, but I realize that's a tall order! Thanks in advance for any advice.

my comment relates to how to make full use of the color gamut available to you it is common to find Halpha many times more abundant in an object than [OIII] or...
I tried using equalize histograms in paint shop pro. It didnt work on the final image jpg, perhaps if I used raw tiffs.....  back to the drawing board  ...
I am pleased to share my first narrowband image, NGC6888 in Ha and OIII. Details and the image are here: http://www.buckeyestargazer.net/New%20Image%201.html...
good job there joel. The S[II] for this object is very faint....HaO3O3 makes a lot of sense if clear skies are almost non-existant. Â look forward to seeing...
