RE: [APML] OT: Virgo/Coma in Color

Fantastic shot Rob!.  Did you get a count of the total number of galaxies
you captured?  I can see you have a little more than a few that are not
marked with the mouseover. But then again, you would have a hugh picture of
NGC text and no galaxies could be seen.

Thanks to those who responded for the nice feedback.
Some of the bright and dark areas in the background
that some of you noticed are just artifactual. They are
the result of my attempts to correct light pollution gradients.
The large chip and fast f-ratio (f5) of the FSQ make for some
substantial gradients. Since the gradients are complex I find
that for me manual correction works best. Its time consuming
though. The exposures were LRGB = 180:60:30:30. I used my
multiple luminance layering method where the first LRGB was
created in Maxim and the second LLRGB was composited in PS.
You can read more about the technique at
