I've been shopping AstroMart for Abbe Orthos, and have wound up with
two 5mm Orthos. I'll either trade one of them for a 7mm Ortho, or sell
one of them for 45 bucks & I'll pay the shipping (CONUS). These 5mms
are the black Orion Orthos (even the barrels are black), with the black caps, both top and bottom.
Tonite I just picked out Saturn's Cassini ring, the shadow behind on the rings, the crepe ring, and a cloud band on the planet
with both these 5mm EPs - - - using my f6 8" Dob. These are the sharpest EPs on the planet earth.
