    Default Celestron Ultima 7.5 EP



    Does anyone know the correct sequence for the elements that make up
    the Ultima 7.5 EP? I think I put them back in the wrong positions
    after cleaning.

    Default Celestron Ultima 7.5 EP

    It's ok, I stumbled upon this site
    http://www.weasner.com/etx/techtips/...e_designs.html

    The 5 element plossl makes use of a separate single element that goes
    in first. The 2 double elements just follow the same design as the 4
    element plossle.

    My EP works fine again.
