I was never quite happy with the detail in the head of the Eagle so I reprocessed the data by individually manipulating the original seperate colour frames.
Previously the brightness of the star and the slightly bloated blue channel (only noticable under extreme enlargement) had produced a bright halo that was over-whelming some features behind the glow of the star left of centre. Well, I went back to the original data stacks and worked on the stars in the blue frame to reduce the halo. There was indeed some detail visible in the green and red channels close to the star so I enhanced these a tad and recombined. I then enlarged just that bit of the image 3X and used shadow highlights, curves and sharpening to reveal that indeed there is some more feature detail to be seen under the glow of the bright star, I then reduced it back down in size and recombined with the original image. I then colour balanced the whole image to look like the Hubble shot a bit more just for effect :P
The detail is real as it can be seen (much more clearly) in the Hubble shot. Previously this detail had been all but obliterated by the blue bloat and bright glow of the star - cool huh?

Now I think that is as much as I can extract from this data, to get better res I will need a bigger scope and better seeing like say on top of Pic du Midi :P
