    "With an optional camera adapter it may be used as a 1,540mm f12.1 ultra-telephoto lens for photography with common 35mm SLR cameras, or for CCD imaging with a number of compatible cameras."

    I don't know enough about these things to comment with anything meaningful other than I'd like one of these to play with. The camera mount would be a must.
    I've thought about buy a telescope for my boy(and me too), but never do because I'm not sure what to get. There are some cheap telescopes on the net, but I would happily spend another $100 for one that justifies the extra price.

    [The] telescope optical tube assembly may be quickly detached from the Equatorial Mount for use as a portable telephoto lens (some sort of support is suggested)...
    No s**t Sherlock!

    Interesting; I'd be curious too see a test on exactly how good the optics are in this item. The downside to using it as a super-telephoto is the fixed aperture of f12.1 (Common to all catadioptric lenses), which is actually somewhat slower than most (More commonly around f8 - 10). It's likely that modern autofocus systems would have a lot of difficulty with such a small aperture, even in the brightest conditions.
