With other IIS members submitting great Eagle Nebula shots, I thought Id re-do a deep imaging session I did on it 2 months back.
The original image was 7x5 mins @iso 800, 10 inch F5.6 scope hand guided. Modded 350D DSLR with UHCS, and UV/IR filter, MPCC.I used Photoshop set gray point to neutralise the strong red colouring I got so as to allow subtle changes in hure to appear, then enhanced saturation to bring that out, while keeping levels quite low. Now I can see the areas where hydrogen emission (red) is prominent, and others where oxygen is prominent greenish blue.
The 2nd image is a deep version of the same original masked with a shallower version to preserve inner detail and also outer faint regions.
