    I am looking for a digital Camera under $400 that is good for taking
    very long exposure shots of the night sky. I just can't find a digital
    camera with these slow shutter speeds(possibly up to an hour or more).

    You need something with lowest noise possible especially on long exposures
    that has the highest pixel count you can get for your money. God knows what.
    Isnt there an astronomy group that have already got that particular T shirt?
    Longer than say 20 secs you use B setting and take as long as you want.

    Most astrophotographers now take multiple shorter exposures and 'stack' them
    to get the benefit of long exposure times without suffering from the
    increased noise that would be experienced with a long single exposure.

    Software is available for auto stacking the multiple images.

    And the one that gave a talk at our club uses a webcam mounted on his
    telescope, not a conventional digital camera.
    And the results the chap got from his telescope, webcam and the software
    were astonishing.

    Yes, that is also an option. As I understand it, in general the webcams need
    a hack so that the basic exposure time is increased from 1/25 per 'frame' to
    something more suited for astrophotography. Details can be found at the
    QuickCam and Unconventional Imaging Astronomy Group website at

    Canon made a astrophoto camera with the IR filter removed. You should
    look for a used one.

    That can work if you stack them with Registax.

    Right now there's one on ebay for $200 and a few days to go. But if
    you look around you might find one. The model is Canon EOS 20Da

    I think I have mentioned once before (in some thread) that one of good
    places to look for cheap price is a *local* "craigslist"
    (www.craigslist.com) and go from there

    BTW, Craisglist may only available in US so if you live outside of US then
    you may have to find other source. Or, here in US I saw Canon 20D was
    selling for at little as $200, and of cource some may ask for thing about
    same or even more expensive than new. But in most cases, people usually ask
    for around 1/2 to 1/3 of the original price.

    I imagine there is but I have only used Registax and it works well and is
    free.
