The Crescent Nebula, also known as NGC 6888, is approximately 4,700 light-years away. This shot was taken with my Celestron N11GPS SCT using the Hyperstar 3 and the "monofied" Nikon d90 with an Ha narrowband filter installed. The image is a stack of 30 second subs. Color was artificially added using Photoshop to make for a more interesting and representative image.
