Steve. I tried a 5mm orion edge against a 5mm and 3.5mm nagler, and the orion was
too soft, with only 2 mushy belts on jupiter, in a 6" mak and sct, compared to the tv's.
I actually far prefered a GSO 9mm plossel (a very underrated ep) barlowed.
Very dissapointing, though the 9mm and 14.5 Orions where great on globulars.
Cheers and hope this helps.
