Default ASTRO: M77 with color data

I managed to get some color data for the black and white image I posted
a while back. Colors look a bit off with a H-alpha pink to the center.
I seem to have trouble with those low in the sky. Green channel is
always weak at low elevations. I'd think blue would suffer the most
from this but I'm seeing green fade. Think I'll try more time for green
and see if that helps. In the meantime this will have to do.

14" LX200R@f/10, L=10x5' RGB=3x5' all binned 2x2, STL-11000M, Paramount ME

Correct domain name is arvig and it is net not com. Prefix is correct.
Third character is a zero rather than a capital "Oh".

That's a beauty, Rick. Good work.

Hey, a galaxy! And a good one too. I'd wish it was already spring and I
could go for all those nice galaxies again (weather permitting, the last two
years spring was mostly cloudy).
