    Default televue 5x powermate



    i am considering getting one of the 5x powermates to go with my ed80
    refractor. they say that these are primarily used with short focal length
    refractors. the ed80 is 7.5 fl. i was hoping to use it to do prime focus
    photography. now i am wondering if this is a wise investment.
    regards,
    john

    I have a Pronto, 480mm focus length, the 5x Powermate is a must for planets,
    unless I want to look through tiny, pip holed 4 mm eypieces.

    A barlow is necessary with a Pronto to get reasonable magnifications but a 2x
    like an Ultima does a fine job.
