Astrophotography With The Nikon D3000
This is a Celestron CPC 1100 (11") Schmidt-Cassegrain Telescope with GPS controller. It's sitting on a Scope Buggy. This sucker's heavy, so the buggy is great for taking the scope out to the front yard. My Nikon D3000 (Nikon's cheapest DSLR) is mounted on the back of the scope.
Moonshot! For sheer drama I like the thin crescent, but a half-moon is not too bad. The full moon is too bright and feature-less for my taste. This shot was taken at 100 ISO with a 1/30 second shutter speed. The f-stop is determined by the scope, and I don't know what it is.
This is the Horse Head Nebula in the constellation Orion. ISO is 1600 and shutter speed is 30 seconds. At these settings, camera "noise" is not too bad.
Here's the Horse Head at 96 seconds. Camera noise is very noticeable in this shot.
These were the best of 40-something photos I took this morning. I got outside about 3 a.m. and came back in about 5 a.m. Temps were in the mid-30's, so you know I was freezing my ass off and was glad to come in for a pot of hot coffee. I also got a shot of Saturn, but it was poorly focused and blurry. Also, Saturn isn't at its best angle right now to see its rings.
I'm just starting out on this astrophotography thing, so I'll post more pics as I learn about what's in the sky and how to take better pictures.
