    Good job.
    A really good webcam for astronomy is the Philips Too Cam Pro.
    You can unscrew the lens and
    you can use metal lathe on a piece of bronze to screw it inside and fit itself in your telescopes holder.
    Another good webcam is the Quickcam B/N: very good ccd, but... the product is now discontinued.

    Black Sky for you :-) and good observation.
