The North American Nebula in the constellation Cygnus. The bright star just below center is Deneb. The photo covers the northern area of Cygnus. The bright red nebula is the North American Nebula, aptly named due to its distinctive shape. The shot is approximately 25 degrees wide, roughly the same width as the Big Dipper. Shot with my 50mm Canon f2.5 at an aperture of 3.5. Other details at left.

Shot piggyback on the Doc G 12" LX200 observatory of the Madison Astronomical Society, a professionally mounted telescope.

Once again, a great shot. You're having WAYYY too much fun. I'd expect three minutes at ISO400 to result in a fair amount of grain on a 10D, so I'm curious to know how much of the shot is noise vs. stars. It also looks like you're getting a LOT of purple fringing with that lens (blue stars ain't THAT blue). Although it's not as wide, I suspect that your 70-200 wouldn't do that. You might also try a longer exposure at f/8.
