Hi all:

Here is another wide field taken with a Pentax 67 55mm medium format camera lens and FLI camera. This one includes 40 minutes each of RGB taken in 5 minute subs plus about 2 hours of Ha in 15 minute subs. The Ha was blended with the R channel before a regular RGB combine in Photoshop. Both this image and the image of Sagittarius I posted earlier were taken on August 10 and 12.

The field is pretty much the entire "Northern Cross" portion of Cygnus, plus Lyra. This particular image covers a 36 by 24 degree portion of the sky. The density of the Milky Way star clouds is just amazing to me. The compressed version loses a lot, so if you have a minute, poke around the full resoultion version here:
