Tom -
What mount are you using for this? Also, what guide controller (you didn't manually track those, did you)?

Jimmy,
Fortunately the camera is easier to use than the model number is to remember: DMK 21AU04. They came out with USB2 last November, and that's when I bought it. Mine is 640x480 pixels. I think Chris has the 1024x768 model, which offers more coverage for subjects like the moon, but has a max frame rate of 30 frames per second rather than 60.
I have no interest in deep-sky imaging with a Webcam. If I want to do that, I'll get a CCD camera. I'm sure there are ways to force it to do good long exposures.
The RGB filters are expensive. I bought Astronomik fitlers per the consensus on Cloudynights for ~$200. Then you need a filter wheel, and I'm perfectly satisfied with the manual one I bought from Orion for another $200. Add the camera, and the imaging setup costs about $800. The reasons to spend all that more coin over a ToUCam is that the high frame rates are not compressed and it's a monocrhome, so you don't lose resolution due to the Bayer matrix.

Hi Tom,
My first response was "Wow!" which I followed up in my mind with the questions that Gene ask. Now I'm curious as to which model of their monochrome cameras do you have? Have you tried or is the camera capable of any good deep sky results (I'm guessing yes as max shutter is 60 minutes? Bottom line, do you like it? Have you looked at their color cameras? Etc, etc, etc...
