Finished a quick process on the M16 narrowband from last night. A number of problems (probably mostly due to me) with the resulting image. First, despite 25 x 60" subs of SII there just doesn't seem to be much of it there at all, could be this target but maybe it just needs more time. I can see it in the stacked SII image but bringing it out is almost impossible without destroying the image; so I have left the SII out for now. What I have posted to Astrobin is a Bi-Colour version (with Ha - Red, and OIII - Green). I tried a Hubble pallet and was not happy with it and it needs more work.
I know there is more there but am having trouble bring it out without making a mess of it.
These were shot at Unity (Gain 139, Offset 31 (I think or was it 21)). Looking at it now on Astrobin I am thinking the stars look too green and I need to turn the saturation down a hair but not now. The Astrobin histogram looks pretty pathetic. Generally I think it is too dark as well.
I will stick a small one on the bottom here but have a look at the big one and give me your opinions on how I could do it better:
