This is M37, a beautiful open cluster in the constellation Auriga.
I took this shot with my Nikon D3000 and a Celestron 11" Schmitt-Cassegrain telescope, effectively a 2800mm, f/10 prime-focus lens. ISO 1600 and a 30 second exposure. I think I could really sharpen these shots up with an autoguider. Perhaps when I go back to work.
