    Who can clean out an old Zeiss 8x30B?

    Jas - The Zeiss 8x30 B monocular is a little jewel. However, do-it-yourselfers can easily botch up a job. The exterior of these almost without exception is pristine, but you noticed some degrading of the prisms, which reduces brightness. Many of these have passed through my hands over the...

    1972 West German 15x60 question

    My Zeiss archival info says that generation has T coating, Zeiss's proprietary coating. That I believe means it is multi-coated.

    That of which shall not be spoken......

    Glad you enjoyed my comments. Every place on earth possesses its own uniqueness. I've had friends who have visited the Great Barrier Reef, and they describe its features using superlatives. Montana just broke a million residents. So with this much land mass, there is plenty of space to roam...

    That of which shall not be spoken......

    On the subject of bald and golden eagles, several days ago I left WSS to go to the nearest Home Depot store which is 75 miles away in Montana's state capitol, Helena. It was a most unusual trip. Most of Montana is under a thick blanket of snow. Yet the highways were summer time bare. I have...

    That of which shall not be spoken......

    OK Bob - Buffalo chips? Buffalo (American Bison) in general? Sure, I can speak to both. My matriculation from Buffalo High was just a prelude to keeping both in my life where I was continuously connected to buffalo. People who know little about what are called buffalo chips find their use...

    That of which shall not be spoken......

    Rath - In response to your question, most monoculars cannot compete with the current alpha binoculars, unless several variables are included: weight, size, intended purpose, etc. A past thread discussed extenders, which are just another form of a monocular. And so are spotting scopes, a...

    That of which shall not be spoken......

    CliveP - Your thread on the monocular interests me. It begins with almost a Shakespearean quality - not quite Hamlet but its legitimacy brings out comments from the "Crown" (Lee) and the penal colony where England sent many of its bad boys (Rathaus), and even our erudite American (Brock) joins...

    Binoculars for eyeglass wearers, over the decades

    Very nice post, Arthur. Some comments. I'm a dedicated eye glass wearer, not by choice but because of astigmatism. Even at age 80 my corrected vision is 20/20. I have been dealing with the reduced FOV for almost 60 years, and have jury rigged countless number of binoculars to try to get...

    Golden Eagles

    Here in Montana, where there is an abundance of Golden Eagles, attacks on all sorts of animals, both large and small, are very common. Domestic sheep, and particularly lambs, are very vulnerable to depredation. When large sheep herds fed mostly on public lands, the sheep men waged an...

    8x42 Zeiss Terra ED vs Nikon Monarch 7 - detailed comparison from an Optical Engineer

    Brock - Regarding your comment about Bill (full of himself), perhaps BF has a budget for sending people to charm school, which could include many of us. Bill the navy guy, as I like to call him, has added to BF in a special way, viz., he helps keep many of us reality bound as we share our...

    The Eye-Brain Connection

    Have been dormant for a while, particularly after reading this thread in its entirety. There was nothing in the curriculum of Buffalo High which prepared any of us to add intelligence to the eye and the brain's connection to binoculars. After all we were the lads who had difficulty...

    West German Zeiss 15x60

    Garymh - nothing like being where the action is taking place. Hope you aren't inundated with all kinds of Zeiss related queries, but I happen to have one. Are you game for a response? My story. When Zeiss still made their outstanding 15x60 B porro, I bought one (new) and have protected it...

    News from Leica

    Simpler doesn't equate to "cheaper" or "less desirable" (my quotation marks), but this central do-it-all in focusing, in reality an elegant mechanical monstrosity, is why all these focusing problems emanate from these overpriced binoculars. Lecia is just paying homage to what experienced...

    A binocular mystery

    What I am going to write will step on some toes for sure. Or irritate some folks in BF land. Or be unconvincing at best. But here goes. Why have binocular manufacturers today virtually ignored the most useful binocular ever designed, viz., the 7x35? Does not the 5 mm exit pupil accommodate...

    Any of you guys use a filter?

    extudiant - Your posting puzzles me. 1. "Scope objectives don't need protection." Then why do they all come with caps? 2. "add another surface for condensation..." If the condensation falls on the filter, it won't occur on the objective lens. Of course how far the objective lens is recessed...

    Any of you guys use a filter?

    Ron & Hermann - for years I didn't use filters on my spotting scopes, which were mostly B&L and Bushnell brands. Then as I acquired more expensive scopes, filters became more of an issue. I don't take pictures with my scopes but rather use the filters to protect the objective lens. Most of my...

    Scope Lens Cleaning Equipment

    John - the thought just occurred to me that there was a simple way you wouldn't have to clean your spotting scope's objective lens at all. Simply screw on a quality filter (UV, etc.) and leave it in place. Many older spotting scopes, i.e., the B&L Balscope Senior, have a coarse thread system...

    Using the Zeiss Dialyt 18x45 in the field - impressions

    Arthur - Hermann is correct. The scope I am using is the Dialyt 18x45x65 MM. You will see in my post #2, I include all the numbers. Sorry if I created some confusion. When the Dialyt first came out, I thought it should be a 15x45 zoom rather than an 18x45 zoom - to have a wider field. But of...

    Using the Zeiss Dialyt 18x45 in the field - impressions

    First, because I have the time, and second because I become somewhat bored when I have the time, and third because I have become intrigued with the Zeiss Dialyt 18x45x 65 MM spotting scope, I decided to test it against a spotting scope with an impeccable reputation, the Swarovski 65 MM HD with...

    I'm getting some NOS 10x35 EII. Is there a particular version to get? Serial #?

    Rath - When Nikon began to market the SEs and the EIIs, I purchased every model, some a couple of times that went to friends. Their optical quality was high. First came the SE 10x42, then the SE 8x32, and finally the SE 12x50. Soon the EIIs came with the 8x30 and then the 10x35. Eventually...

    Collecting Bushnell/ Bausch & Lomb binoculars

    Bill - Read "Boots & Saddles?" Of course. Elizabeth Custer spent almost her entire life memorializing her husband, George Armstrong Custer, and she was very good at it. She was well-educated, intelligent, photogenic, and a "true believer" in her husband's military ability. Interestingly...

    Scope Lens Cleaning Equipment

    John - Micro-weave clothes are inexpensive and available almost anywhere. Those and most any liquid lens cleaner will do a good job. Do not spray on the lens but rather on the cloth. One's breath will do in a pinch. I keep cloths separate in ziplock bags to help maintain cleanliness. Salt...
