Thanks Brian,
I really appreciate you telling me about the Carton /CircleT ortho,
there appears to be very little info on the Carton eps....
I purchased it many years ago to fill the gap for a 60mm Amasco refractor that came with .96 Kellners 25 & 6mm made in Japan.
The 25mm Kellner and 9mm Carton ortho, both have great light transmission and are great looking at the moon through a Orion ED80!
