    Let’s talk about eyecups (comfort, dimensions, preferences, etc.)

    There are also numerous aftermarket (or "non-market") eyecups available, that one can modify for custom fit . . . https://www.ebay.com/itm/155918788217?itmmeta=01HVSQAFCD10YWVT5MVBMTY5M1&hash=item244d7be679:g:eckAAOSw9gRZ-usF

    . I have purchased over a dozen "vintage" binoculars from ebay. I have a small collection of WW1 and WW2 binoculars - Zeiss, Leitz, Hensoldt, Barr&Stroud, Bausch and Lomb, etc. . When shopping ebay: note country of origin (difficult to get a refund from several foreign countries) read...

    Best marine binoculars?

    . I have purchased over a dozen binoculars from ebay, "sight unseen" . First, I judge by the seller's "feedback" . . . ie. if the seller's feedback is 100% over a few hundred sales and several years, I judge him trustworthy. If it is a "new" seller, or has a lower feedback, then you roll the...

    Best marine binoculars?

    Again, permit me to clarify . . . . . . . . the only opportunity to try other binoculars in a "dark sky" environment, was at a star party. I do not own a boat, and I very seldom go out on the ocean. I listed the binoculars that I used, from my memory, about 10 years ago. Obviously, I should...

    Zeiss WW2 Binocular, help needed

    Several models of binoculars built for naval forces had small canisters of silica gel for removal of moisture. There were several companies that manufactured binoculars for naval application - Zeiss, Leitz, Emil Busch, Hensoldt, etc.

    Ocular Lens Size

    I am not an Optical Physicist. I have several binoculars with ocular sizes ranging from about 8mm to 23mm. Using a variety of these in widely varying circumstances, the larger the diameter of the ocular lens, more comfortable to "hand-hold", and make for much easier viewing.

    Best marine binoculars?

    150 meters I merely mentioned that to illustrate that these were completely waterproof. (I was not suggesting that anyone take them to 150 meters depth to find out) Depth of field: I have my 7x50 "Fat Boys" focused to read script at a distance of 150-200 meters, and when viewing stars in the...

    But, if you are looking for the BEST 8x60 glasses . . . . . These are known as Zeiss "Captain's Glasses", or "8x60 Fat Ones" There were only a few made before the end of WW2, and exclusively issued to the more successful U-boat Captains. The focus adjustment is identical to the 7x50 "Fat Ones"...
