I decided to put the deep capability of the 10D to a tough test...the Which Head Nebula (IC2118). I took about 74 minutes of exposures with the Canon 10D at ISO800 through the f/3.3 Tak Epsilon 160. See my web page for details and higher resolution images:

Rick,

Very impressive. You are doing some great work with the 10D.

Rick, you take some incredible shots! I have downloaded many of your images into a file that I use for my screen saver.
What kind of skies do you have there in Scottsdale? Surely all these great shots aren't from suberbia with 3.0 mag limit skies? All the best - Glenn

Rick,

Wonderful image! Because the nebula (plus sky) is only slightly brighter than the sky, a very high signal-to-noise ratio is required to produce such an image, which is very challenging for films. Certainly you and your 10D did a good job.

Do you want to try mosaic? There are lots of faint nebulas around the witch head. Perhaps you can make a 2X2 or 3X3 wide-field mosaic. This is my witchhead:
