    Default Orion 100mm ED



    I would like to here opinions from those who own the Orion 100mm ED. I
    would like to use the scope for wide field imaging with a Canon 20D and
    Toucam 840. Also I would like to use it for a guide scope with the ST-5.

    A friend of mine bought ED100---he bought a "clearance" one directly from
    Orion. It arrived in perfect condition. I've compared to my ED80 with
    which I am extremely pleased---the difference is pretty slight. It performs
    very well and the false color---there is some---is very, very minmal. The
    mechanics are nice too. The focuser is very smooth---far superior to R&P---

    Now the usual Astromart comments...is it worth the price difference of the
    ED80? Maybe. For imaging? Hum. I think my ED80 outperforms his ED100
    optically but that can be an OTA variation. But a used ED80 at less than
    half the price of the 100 is quite the deal in my opinion.

    Go for a Tele Vue 102 or NP 101. It will mop the floor with both of them.

    You neglect to mention that the TV 102 and NP 101 are a few grand more
    than the ED100/ED80.

    I don't own one, however, I do have some comments..... ;-)

    At 900mm focal length it won't give a super wide field with the 20D, but it
    will be able to frame the entire Orion sword complex. If you are using the
    webcam for planets, the 100ED is probably not a good choice either. There
    will be violet.

    I've done a little bit of imaging with a Vixen 102ED F9 refractor (920mm),
    and decided that an 8" F4 reflector with coma corrector is a _much_ better
    solution for DSLR and webcamming. The larger aperture gives much faster
    results for deep sky with the DSLR, and the total lack of chromatic
    aberation gives better results for planets with the webcam.

    The Hardin Optical Starhoc 8-4 costs about a 3rd the price of the 100ED as
    well. But you do have to add the coma corrector. The Hardin R&P focuser is a
    clone of the Vixen, so all the accessories are plug and play. I use the
    Vixen CC and Direct Wide Photo Adapter for EOS cameras (the CC screws into
    the scope side of the DW, and the T-ring screws onto the camera side of the
    DW.)

    All that said, the 100ED would be a better guide scope, but frankly the 80ED
    would be an even better choice as it surely weighs less, is shorter, and a
    CCD guide camera doesn't require the longer focal length. The 80ED will also
    give a wider field at 600mm focal length. I also have the 80ED, and I'm
    leaning toward keeping that, and selling the 102. The main reason I like the
    102 more than the 80, is for visual use on planets in winter.

    HTH,
    Stephen

    Years from now we will be talking about how the Asian 100ED scopes
    destroyed the American manufactures like ...uhm what was their names?

    Notice how prices for supposely superior American refractors have been
    steadily declining on Astromart?

    It is just a matter of time...

    Nope...just someone who in the past has anticipated future trends to a
    sucessful degree.

    The true test of any telescope is in its star test.

    A fact that most wallet obsessed refractor owners tend to forget.

    It happens in any hobby...those who can't compensate by throwing money
    at showcase equipment.

    For every Asian ED refractor that is sold, there is one less TV or AP
    sold.

    And there are ALOT of Asian ED refractors being sold with larger ones
    sooner.

    Do the sales forecast and the numbers speak for theirselves.
