ASTRO: NGC 7331 - color
An LRGB exposure at 18:10:10:15 minutes using an SBIG STL-1301E thru a 20-in
F/8.1 RC Cass. Considering the sky conditions these exposures were way too
short, especially the color data. I'll have to give this group another try.
I'll also post black & white and ID'ed versions.
