Astropics With The Nikon D3000
Risking bone-numbing cold this morning, Carpenter hooked up his Nikon D3000 (their cheapest DSLR) to the back end of a Celestron 11" Schmidt-Cassegrain telescope(f/10) to bring you these shots of things in the night sky. Viewing conditions were bad--50% cloud cover and extremely turbulent atmosphere. Above, this first shot of the crescent moon is at ISO 200 and 1/60 second shutter speed.
1/20 second, ISO 200. This is the sharpest focus that the clouds and atmosphere would allow.
This shot is so blurry, it's hard to tell if that's Saturn or a UFO. Out of ten or so shots, this was the best I could get.
This is the great globular cluster in the constellation Hercules. I was shooting through thin clouds, so I'm surprised it turned out this well. 30 seconds and ISO 1600.
I took this shot a few nights ago. It's the Orion Nebula. 30 seconds and ISO 1600. Lots of noise (graininess) and tracking could be better.
This is the Andromeda Galaxy, I think, also taken a few nights ago. Mrs. UC refers to galaxies as "smudges". Galaxies, and particularly nebulas, are unimpressive until long-exposure photography brings out highlights and colors.
