Caldwell 33 - NGC6992/5 + IC1340 - Eastern Veil Nebula in Cygnus - 10/08/2012 (Processed stack)

Notice an uneven background light in the lower middle of the image. It could be related to the 40D which seems to leak a little bit of light into long exposures from somewhere. I picked this up doing "darks' during daylight.
