Andromeda Revisited

I had recently posted an M31 - thanks to all for the helpful comments - Warren K. especially. I corrected my error and I believe got better star color and eliminated a blue cast to the background. My red exposure data is usually somewhat intense - in my normal processing I usually attenuate it some and I did so here. So this image pretty much following my normal routine. Not the same level of red as in Warren's, but I am happier with it than my original.

I have attached a mid size image, but a full size image can be accessed at:

The original image with the green channel error can still be accessed for comparison purposes at:

Great shot Jimmyboy. Its quite 3D, the stars in the left side really stream out and give a sense of distance.

Greg, Warren,
Thanks for the comments - and Warren, thanks for the help. Yeah, the Luminance was 18 minutes, but as I mentioned I did combine it with some earlier data (core and galaxy area) - three 6 min subs. But yeah, 18 plus 18 was it for the luminance.

The stars are a bit funky from something going on in the cheap SLR lens. As I recall, even very short test exposures showed the stars a bit out of shape.
