I have 2 crappy EPs that came with my refractor. Nothing at all written on them though except for the size, so I don't know what they are. On axis they produce stunning images of jupiter...real contrasty, crisp excellent! But they throw out like a lens flare around jupiter.....like a ring of light, only it's not perfectly round, kind of a random shaped ring of light. Off axis their RS! Turns jupiter into a comet. When you look to see the coatings on the lenses...I can't see any coatings at all....the lenses look clear to me.
