NGC 7331: NGC 7331 is the dominant member in what is also known as the Deer Lick Group. This relatively close grouping is towards the constellation Pegasus. It is one of the brighter galaxies "missed" in Messier's catalog. At one time, it was thought the Milky Way may look like this galaxy, but more recent measurements suggest more of a bar shape for our galaxy.
Other Catalogs: Caldwell 30
Right Ascension: 22h 37m

Processing Notes: Data acquisition with CCDSoft. Reduction, and alignment with CCDStack. Subs combined in Sigma Combine. RGB combined in CCDStack with a ratio of 1:1.06:1.85 to compensate for atmospheric extinction. L and RGB images stretched and tweaked separately in Photoshop and combined with layers. Significant smoothing and increase in color saturation on RGB and repair of several overbloomed stars in the L image

Additional Comments: This was one of the first "totally-remote" images now that internet access is available at the observatory.
