    Monarch M7 8x42 problem

    Perhaps what you are experiencing is a combination of factors= looking at a vase of flowers that is close to you ? Consider the fact that the eyes at that point irrespective of using binoculars are essentially "coming closer together " in that they have to start converging in pupillary...

    Binocular repairs/service

    Just curious as to the "repair registration is undergoing maintenance. It will be available soon again" statement- any time stamp as to when it was first posted? Pat

    Opaque and greenish view

    this off the net "It's not advisable to use them on plastic parts. As lithium is based on petroleum, it tends to speed up the decay of rubber and plastic components. Lithium-based grease can withstand high temperatures and are perfect for cars, heavy machinery, and guns."...

    Opaque and greenish view

    I don't have any specs or even the knowledge as to what a "damping grease" is in comparison to other forms of grease. But a helical thread has a large contact area and that would seem to me to work against a thick grease. This might provide ample range of thickness...

    Swift Audubon HR/5 question

    Is there any other brand other than swift that uses that technique with the 4 hidden flaps in the leatherette to access external adjust of the prism trays? The rest seem to go through the rear prism covers on the B&L type frame

    Opaque and greenish view

    I'd also use some light coming through the eyepiece while moving it around the EP and taking the same look through the objective. A small light source that can be placed to the objective and moved about may also aid in the diagnosis. Always better for the doctor to know pertinent info on the...

    Nikon EII general question- Zeiss or B&L framed bino?

    Perhaps the edge blackening has more to do with the earlier and largely uncoated surfaces and the cumulative loss of throughput. A small gain in brightness might be perceived from the low starting point. With the higher transmission nature of the improved coatings, the eye can't perceive the...

    Nikon EII general question- Zeiss or B&L framed bino?

    William Lewis- it absolutely answers the question, it is indeed a Zeiss framed bino (German pattern) and it does not appear to have any means other than eccentrics on the objective to adjust alignment so the machining has to be done precisely. A well made yet classic build. Thanks for digging up...

    Nikon EII general question- Zeiss or B&L framed bino?

    Since I have never had one in my hands, can someone enlighten me as to the design construction- are the prisms on a detachable tray as in Bausch and Lomb (American pattern) frames or is it a Zeiss frame with the prism dropped into slots milled in the bino frame a la German pattern binos. With...

    Nikon 8x30 EII - Strange Issue Inside Lens?

    on the dark side, I seem to recall a recent Japan buy of an EII from a reputable shop and the buyer had a similar problem- apparently new older stock that was stored poorly- the conditions were ripe for a fungal growth. As to "Balsam separation"- they use synthetic now adhesive- far more...

    Curious about old Sans & Streiffe binoculars (#995)

    if you google "streamline brand binoculars" you will find the info - most of what I've seen are 7x35's but the 10x variant was a new one to me... well made, heavy, BaK4 prisms- coating seem to be single mag coating so not that bright- sharp, with a good focuser. The weird right objective is the...

    Information on these binoculars if possible please.

    this from a contributor to the bino forums at cloudy nights where I posted the question on your 7x35's. "Given the exact same t.v.-screen "KOC" logo - plus that "Kana" part of the brand name - I'm thinking that sweet-lookin' Kanako was made by Kanagawa. I would guess it to be mid-to-late-'50s...

    Information on these binoculars if possible please.

    wonder if that's "Kamako" an early version of kamakura koki perhaps? Nice looking binos .Wonder if there are JB/JE #'s there somewhere looks to be maybe mid 60's so there may be JB/JE. BK7 or BaK 4 prisms?

    Vintage Vixen Ultima - need help

    I have 2 swift ultralites (8x42) that look a lot like the vixen ultimas, not to mention the celestron ultimas (the first generation, not current iteration). It may be later than that perhaps the early/mid 90's. Same FOV, same eyecups, also has JB56 on the forward axle lugs. Excellent focuser...

    Vixen @Six 6x18: quirky and surprising pocket binocular

    That reminds my of the Fuji Glimpz 5x21 bino- a cheap yet quite decent small bino (no longer made) which for me, a wearer of glasses, comes close to having a full FOV! (supposed ER 13.2mm) Regards, Pat

    Checking Collimation

    I'd ask multiple persons to look through the bino's as they are pointing at a fixed horizontal line- the brickwork or eaves of a building while the binos are on a tripod- that would allow you to move the eyes away from the bino slightly to magnify (if any) mis alignment. Have you other binos...

    Advice on a good 12x50+ that won't break the bank

    In the case of those Obie binos- I'd wager the clamp screw - it's either tightened down, then a setscew locks it in place- either the setscrew was insufficiently tightened which allowed the clamp screw to turn and the arms started to flex a mite because of the looser tolerance. They...

    Advice on a good 12x50+ that won't break the bank

    Hopster; A shame you had to send it back as it sounds the fix would have been straightforward for a person that's worked on classic porros over the years. The clamp screw that binds the 2 eyepieces and arms together to the focus mechanism sounds loose and that 's fairly easy to deal with- as to...

    Still using your HR/5?

    Are they the same body? I'd be tempted to try a eyepiece/focuser changeover and take another cross check. Might the difference be in the eyepieces? Pat
