Quote:24mm Hyperion does indeed seem to offer the widest possibe true field in a 1.25" eyepiece, and much much wider than at lest the generic (sold under many brand name) 32mm Plossls that I bought.

Quote: How about the 24mm Panoptics? From everything I've read over the years in the binoviewer forum, the 24Pans are reputed to have the widest true field available in a 1.25" eyepiece.
Quote:You can get a little wider with Ultrascopic 35 (field stop 29mm), Hyperion 31 with 1.25" nosepiece (field stop 31mm) given you have vignetting.Tammy
Quote:This has already been tested and reported. Once you go past 28mm, there is no more improvement in true field size.
