Constellation - Aquila
Click Images for Larger Version
This is the first astrophoto I took with my new lens that I did "right." There's not too much explanation for this, but I very unfortunately flat-fielded out most of the Milky Way. And because of the moon and where this constellation is, I'm not sure I'll get another shot at this in 2007. Oh yeah, and I got about half of the very small constellation Delphinus.
