    Acuter and Celestron 16-48x65, 20-60x80 & 22-67x100 Spotting Scopes
    have identical optics, bodies and cases. The only difference, apart
    from the badges, is the sight tube for quick targeting on the side of
    the Celestron models which is absent on the Acuters. (While this is
    not essential for daylight use it is very useful if the scope is used
    for stargazing.) The rubber eyecup can be removed from the eyepiece to
    reveal a 42mm, 0.75mm pitch thread.

    Conversion Lens Adapter LA-DC52G is required for the Canon Powershot
    A590 IS. A generic adaptor is available on eBay for 570/590 - this has
    a 52mm internal thread and can be fitted with a 52/42(0.75) adaptor.
    The adaptor fits the spotting scopes mentioned and also the Zenith
    Biolam microscope camera adaptor. Note that the Biolam can only be
    used with the 7x eyepiece – the 15x sits too high in the camera
    adaptor and will hit the lens surround as it extends! The digital zoom
    feature on the Canon is very handy for accurate focusing when
    digiscoping.

    What do you care? You don't take any photographs. Hell, you don't even own
    a camera. You're just a troll living out your pathetic imaginary
    basement-life on newsgroups and forums, spewing your inane nonsense
    incessantly.
