Well as usual the purchase of my new clear glass modified Canon 40D (by CN's own jcham21 - Thanks James!) a while back brought on lots of cloudy rainy hazy weather although in all fairness we have had lots of that sort of weather this year. In any case we finally got a break in the weather that corresponded to favorable moon conditions and a weekend so I was FINALLY able to get some images with the new camera. All of these were captured on Friday night/Saturday moring (8/29-8/30) until 4:30AM and Saturday night/Sunday morning (8/30-8/31) until a little after 3:00 AM.
I am REALLY happy with the camera. It certainly seems to be performing much better with Ha nebulosity than my unmodified 300D was. The live view focusing is absolutely awesome! I can't wait to get in some more time imaging with it. James seems to have done a great job modifying it. I have used it for quite a bit of conventional photography (weather - remember?) with an X-nite CC1 filter and it works great for that as well. Autofocus works flawlessly and with the filter colors seem to be quite correct using auto white balance.
First up is M17/The Swan/Omega Nebula. Poorly framed, but it was getting low in the sky and was nearly below the top of the south wall of my observatory and I was hurrying to get some subs before it got too low and in case the weather turned so I just made sure the nebula was visible in the viewfinder and started a run. M17 is a stack of nine 45 second images calibrated with 5 darks, no flats or bias. I think it isn't too bad for the relatively short subs and short stack. This image and the following two were all shot with the following equipment:
Orion 8" F4.9 Newt w/Moonlite motorized focuser
Baader MPCC
Losmandy G-11 mount
Orion 120ST Guidescope/SAC-7b Guide cam
Canon EOS Utility for image capture

Here is IC5145 The Cocoon Nebula. This is my least favorite of the 3 posted here becuase it really needed longer subs and a LOT more total exposure but clouds kept moving in. I think some of these subs may have been degraded by high hazy clouds as well. This is a stack of 7 frames of 5 minutes each at ISO 800 with 5 darks and no flats or bias frames.

Last but not least here is M52 and The Bubble Nebula. I may have overdone the red in the Bubble a bit. This one is closer to reasonable total and sub exposure times - the best 17 of 42 5 minute subs at ISO 800 with 5 darks and no bias or flat frames. I usually try to shoot at least 4 hours on an object and expect 3 hours or so worth of the frames to be in my final stack but high cloudiness kept moving through and that kept a lot of my subs from being unusable. 10 minute subs would probably have helped as well but I am pretty pleased with the result anyway.

Very nice indeed. How do you like the Orion scope? I'm thinking of buying their 10" F/4.7 scope.

cweinhei,
I like the Orion scope. The focuser left a lot to be desired (my scope is prior to the current crayfords) and I replaced that with a MoonLite but in general it is a dandy scope. I think like a lot of the less expensive scopes you tend to get some lemons but Orion seems to have a good return policy so in the end it should be possible to get a good sample.
