My CCD is en-route back to SBIG for repairs, so I had to revert back to my DSLR before bad weather terminated this month's imaging effort.
Here's a wide field of the Witch Head Nebula and Rigel (
1500 px version).
I experimented with using In-Camera Noise Reduction (sacrificing half of my shooting time) and found that it works *much* better than shooting darks separately. This needed a bit more data to really bring out the Witch Head, but alas the weather wasn't cooperative.
Details: 21x 180 sec subs (63 min total lights, 126 min including darks), 135 mm, f/4, ISO 1600, ICNR taken with a Canon 5DmkII and 135 mm f/2L lens unguided on an EQ6PRO.
