HI binastro! thanks for your research for the useful / nonuseful of the " hydrogen proxide" . so bottom line it can be use for cleaning lens but better to use acetone or isopropyl alcohol. the" baader optical fluid" not familiar in israel. as I said to peter the big concern is not to make a damage to lens coating! for me as a vitage bino's colector this issue of clening is importent! for the collimation I will try to fix with the knewledge sources that I found and will inform you and the members on this forum as this issue is challenge me as a colector!

Hi Publin -- probably to fix the collimation will cost more than $70 -- perhaps return them to the seller as faulty?

Publin,
I hope and believe your 10X50s can be fixed. On this forum we are all helpful to each other, we may disagree on many things, but they are minor in the grand scheme of things.
I have consulted Bill Cook on the issues with the repair of older porros many times, and he has helped me as I also have collected older military glass over the years. Bill brings over 40 years in the optics industry and when it comes to repair or collimation he is highly knowledgeable.
We all have different ways to communicate, but the information is there, Bill actually knows what he is talking about since he has repaired thousands of binoculars. Give him a private message, and he can help you perhaps you can do it yourself with some guidance, a small project that will save you some money.
All the best and welcome to the Birdforum binocular forum.
Best Regards,
Andy W.

HI ANDY! thanks for your advice! this bino have a slightly misalignment . in daylight not noticeable almost in night viewing to distence window light can see double image slightly. I have the knowledge how to fix alignment in russian vintage bino'S and I done it with my bino's collection. this sears 10x50 have the setscrew on the barrels [2 in ocular side 2 near the objective lenses] so the fix is more complicated. thanks anyway!

well done, that's impressive
Just scanning through this thread I think the upshot is do not buy optics with fungus, more trouble than it is worth.
Bill seems to have more experience with the innards of optical instruments than most of us, and if carefully perused his cryptic contributions are usually helpful.
In the name of the forum, I will apologize to Bill for the way he was yelled at. If the mods consider this an undue action, they may remove my account.

Agreed on all points.
Some time ago I bought SEARS 7x50 binoculars from America with eyepieces similar to those, but it came with mold inside.
I immediately opened it and disinfected it. Then I calmly cleaned it up and refurbished it. Now I use it a little, but it works very well, it is heavy (1.2Kg - 42oz) but very balanced and ergonomic.
The vision is very broad and neutral, although of low transmittance (perhaps between 70% and 80%).
