    Default Am i on right track???





    Hi all,
    i,m looking into getting extra ep,s and 2x barlow.
    Skysthelimit have been reccomended to me!
    Just wondering how good are their Series 500 plossl ep,s
    and the 2 element 2x achromatic short focal barlow.
    Has anybody had experience with their performance?

    Thanks,

    Steve.......

    Plossls are good at long fl. But the eye relief is about 70% of the fl. So a 10 mm plossl only has about 7 mm of eye relief. That isn't enough for me. My cut off for a plossl is about 20 mm.

    The quality today doesn't vary much between labels. Look at the spec for eye relief, apparent FOV and coatings.
