Subject: M31 - Andromeda Galaxy

Camera: Canon Rebel T1i
Technique: 1 light (30 seconds at 6400 ISO)
Prime focus. Noise reduction in Photoshop

Tonight was a spur of the moment night for astrophotography. Sarah and I were outside enjoying the Perseids when I realized it was the clearest night I’d had in months. So, I set up the telescope in the dark and took some quick shots. This was one of them.

This was one of the brightest (deep sky) objects in the sky so I was able to get away with a single shot (i.e., no stacking), albeit a bit noisy at that high iso. There are a lot of things wrong with this picture such as the focus, star trailing, noise, and vignetting. I attribute all of these things to not having time to prepare. Regardless, I am happy with the outcome. I expect to get much better shots of M31 in the coming months.
