Are short imaging scopes better for binoviewing?Posted By Mike Clemens |
At the far end are scopes with a full 8" - 9" of infocus, permitting a big 2" diagonal and a binoviewer with a 4" optical path length. I think my TEC is like that, and I know my TMB 100/8 was like that.
Below that you can go with the shorter prism diagonals. I don't know anything abut 45 deg prisms or their path lengths. The Baader 2" prism has a shorter path length than full diagonals do.
