Thanks guys.
I don't have an easy EXIF exporter, so here's the manual transcription:
exposure 15s
aperture 2.97
f number f/2.8
iso 1600
There was plenty of exposure, I could have stepped down the iso or the exposure, but the conditions for examining the photo were quite poor, as you can imagine. I made a copy and this is the edited copy, I added a lot of black as the original has an unpretty amount of noise.
I also took a shot straight up and got a lovely view of the Milky Way, though there's lots of noise in that one too.
plt--Night shots are h-a-r-d. Keep at it, they're very rewarding and your camera has much more technological horsepower than mine does. When you learn how to drive it, you're gonna love it.
