M17

Here is another version of M17, the Swan Nebula, but taken with the 10" Newt at f/4. It could have benefitted from a bit more time, but location and timing limited the total exposure to 75 minutes. The image is an RRGB, which works well with H-alpha emission objects. This shot was taken at Chiefland during the September new moon.
