Hi I find a old model Celestron 16x70mm Wide Angle(not Skymaswter 15x70mm) similar in appearance to the Fuji 16x70mm - somebody have some information about- it...
... Instead of "reinventing the wheel" I would suggest using the already established Astronomical Leagues' observing clubs. They have the Binocular Miesier,...
... Ed, My original post was generated as a lighthearted attempt at generating some dialogue. It was never intended to conflict with the various Astronomical...
... Hi Ed My intention was not to imply (although it may have seemed that way) that one method of visual astronomy is "better" then another. As the old saw...
Hi Guys I am looking for any information about the oldest Celestron and Vixen 20 x 80's (I believe of the 80's) that were built with a extra size focal ratio -...
due to many problems with "the bus" (not to mention tx weather), my observing while on tour plan got pretty shut down. The only opportunity was on the way out...
Hi, all, Since things have been slow around here lately, I thought I'd come out of lurking mode and give a short OR from last night's viewing here in western...
Hi Rich, If you can do all that with 16x70s, I look forward with even more interest in the Series 2, 19x90s that Bill Burgess is sending me for test and...
Donald, For me, I can use all the exit pupil I can stand--- up to 5mm or so. With 25x150s I would be wasting one whole expensive mm of pupil :^( I may still...
Rich, So the exit pupil of the 19.2x90 is 4.6875mm. But -- and here Rich, you are going to get one of my famous But . . . Buts -- But while the extra mm...
Hi! My name is Terry, and I have on order that Nikon all-medium size sez so strap down adapter, because I own a pair of 8 x 42's from Selsi, and do not have...
I'll be teaching an online astronomy lab this fall, and for one of the labs, I want the students to rate the optical quality and astronomical suitability of a...
Under most circumstances, I would apply more weight to magnification. Except in only few circumstances, it allows you to see more. Seeing round exit pupils...
Ed: Thanks for your insights. You clearly have much more experience than I do at looking through different binoculars. I've never claimed to be any sort of...
... Hi! My name is Terry, and I have on order that Nikon all-medium size sez so strap down adapter, because I own a pair of 8 x 42's from Selsi, and do not...
I think the idea to go with stability is a better choice. You'd be best off if nobody dismantled their binocs. Squared off or diamond shaped exit pupils can be...
Tom, A discussion of the need for non-destructive means of testing and the limitations that imposes on the end-user would be a valuable lesson. How much can...
Thanks, Florian I was a bit disappointed I couldn't locate 6355 but I suspect it is an object like 6328 with M65 and 66; it lurks at the fringe of being ...
... I have a log note that i've seen 6355 with my old orange Celestron-8. But no note that i've seen it with binoculars. ... There is a brush fire just west of...
Tom, I fully agree with Ed about NOT disassembling those binos! Though, every binocular I've ever disassembled and repaired has collimation mechanisms. And ...
Hi everybody, I'm going to spend some of my vacation under dark Eastern European skies, and I'm taking my trusty 20x80 binocular along for the ride. I've done...
Hello All, I've decided to re-investigate (for the umpteenth time in my 25 years of on-again, off-again interest in amateur astronomy) the prospects for a...
Check the "Bino Cube" folder in the Photos section. It's a double parallelogram mount on a sliding bridged base on cart wheels that sits on a lazy susan...
I posted this inquiry on another group (binocular) but received no response. Maybe someone in this group can help. I am considering purchasing the Burgess...
... Rob: I also own a CPT and I'm curious what you find lacking in Sim's basic concept, though not necessarily its execution. It is remarkably comfortable,...
Thom, I consider Sim's design concept absolutely perfect. The stability of the struts, mainly in the lateral directions, is my only real concern. I used my ...
