Description: NGC 7331 was discovered in 1784 by William Herschel and is part of the "Deer Lick" group of galaxies, some of which are visible in the background (and identified in the large image). These galaxies are not gravitationally bound galaxies, but rather they just happen to be in the same line of sight.
Constellation: Pegasus
Distance: 49 million light years
Apparent Size: 10.2' x 4.2'
Date: 6, 7, & 27 september 2005
Equipment: 12.5" RC @ f/9, ST10XME, AP1200
Exposure: LRGB: 240-90-75-60 minutes (color binned 2x2)
Comments: As you can see from my exposure times, I had problems with some of the color subexposures. The luminance didn't come out as well as I would have liked, either. I'll be redoing this one next year.
