My this is a quiet group.
Given all the "ED" glass roof prisms hatching forth, i thought i would pose the following.
The Celestron 9.5x44 ED was I think the first handheld ED binocular. But the Swift 8.5x44 ED is the oldest one still available new.
A speculative question;
If the Swift ED (its optical quality level & ED glass), were a roof, what would it cost new?
