Hi EDZ and Joe,
Thanks for your comments, especially on the Tascos. The problem is that my Model 124 Tasco is about 40 years old now.
Given all the progress in ED glass and coating technology, as well as eyepiece design by the likes of Nagler and others, in 2008 where does a person turn to for a truly super wide angle low power " survey of the constellation" style binocular. The previously mentioned 2.3x30 units have non-prismatic design as well as issues with exit pupil and eye relief. Based on the reviews I have read here on CN, the 7x32 "Expanse" series, marketed by Vixen, Orion, Celestron, and maybe a few others, seem to have really really tight eye relief, and very modest optical quality. It, like the Tasco, is no longer available.
Bushnell does make a 4x30 xtra-wide-angle clam shaped binocular claiming FOV of 900 feet at 1000 yds, 6 mm exit pupil, and 10 mm of eye relief. The B&H webpage sites roof prism design. Therefore, the Miyauchis I guess are the best thing going then as of May 2008 ?
Hey, what about that new Fujinon 6x30 ED glass compact binocular with the Nagler Ethos eyepieces ? Just kidding..
Paralysis by analysis. That's where I am now. So, does anyone have any other super wide angle binocular recommendations ?
