I took these shots about 2:30 a.m. I used a Celestron 11" Schmidt-Cassegrain scope as a prime lens for my Nikon D3000, shooting in manual mode. Clicking on these pics should make them bigger.
This is M39, a beautiful open cluster in the constellation Cygnus, The Swan. Shutter speed is 30 seconds, with an ISO of 1600.
The Andromeda Galaxy, M31. 25 second exposure at 1600 ISO. I take several shots of everything, and at various exposure times. I also took a 30 second exposure of this galaxy, but the stars "trailed" a bit. I've got to get an autoguider so I can take some seriously long shots.
This is Jupiter, of course. Crappy shot, blown highlights. 1/2 second exposure at 400 ISO. When I backed off the shutter speed to 1/20 second the moons didn't show and Jupiter was still washed out. A shame, too, because the "spot" was clearly visible in the scope. To get a spectacular planet photograph you have to "stack" shots, something I haven't tried yet.
