I finally received the parts to do some LRGB deep sky shots. For my first try I went back to my old friend M51. The sky was pretty bad with peak seeing going down to ~3-4 arc seconds (a lot of twinkle in the stars). The RMS on the guiding was not great but OK ~1.5 arc second, there were also thin high clouds, a first quarter moon as well as a layer of smoke from a "Controlled" burn a few miles away to deal with. But I was anxious to give LRGB deep sky a try so I went for it anyway. Considering the sky conditions the image came out better than I expected. The color is a bit off since I didn't go through the color calibration process yet but the image does have have less color noise and more detail than my previous DSLR image taken on a good night. I still need to learn a lot more on processing these types of images and using the camera.(These old CCDs are difficult to focus with ~10 sec download time between each test).
This image was made with 12, 5 minute subs for each filter (total exposure time ~4 hours minus a couple of subs that were not up to snuff). I also used Dark frames, Bias frames and Flat frames for each filter. I ran the camera a 0 degrees Celsius.

The equipment used was:
Used SBIG 11002 monochrome camera with Filter Wheel
Astrodon LRGB filters
Meade LX200 16 inch Schmidt-Cassegrain telescope.
Astrodon MOAG - for offaxis guiding
Starlight express Lodestar X2 - for the guide camera.
Optec TCF Leo focuser for focusing (This really helped since when you use the Mirror lock on the Meade it changes the focus slightly, but if you don't the focus will drift in less than 1 hour. With the TCF Leo attached I would use the telescope focus, then lock the mirror and the re-adjust the focus with with the mirror lock left engaged. Still a very tedious process with bad seeing and the long download from the CCD).
Mount Astrophysics 1600GTO

Software used
ASCOM platform for device control interface to programs.
Astro - Physics APCC - and associated ASCOM driver for mount control.
PHD - for guiding
Sky-X to tell the telescope where to go.
Pixinsight for processing the Image
SBig Control - to control the filter wheel and camera.

The next step will be to take a bunch of HA subs and learn how to integrate that into the image
