Very cool website Kenny! Thanks for posting it. I had never seen that site before. 
My connection is running terribly right now, so I will watch the video later tonight.
Is that anywhere near Royal Albert Hall, or am I confusing my 1970 Led Zep shows?
I have been dazed and confused for so long it's not true, so I get my concert dates mixed up.

Hi Mike ,
I didn't expect you to catch my post so soon !
Thanks to you for replying so promptly .
I think you may have suffered from a communication breakdown to be so dazed and confused , but a whole lotta love was behind the idea of posting the link .
The location is Shepton Mallet , near bath in Somerset , which is more than a ramble on from the Albert Hall . Whitehall or Albert Steptoe's scrapyard .
I'm sure you will enjoy the short video when you see it .
Kindest Regards
Kenny

Allow me to ramble on here....
Binoculars are truly a stairway to the heavens, and one should never observe during a rainstorm lest one become a fool in the rain. While going to California with friends, I purchased more than 3 monopods (4 sticks essentially), and I had good times bad times with them. How many more times I could wax philosophic about my binocular experiences that even in my time of dying I will fondly recall my binocular days in the light. In fact, on a night flight I got into a heated discussion with an observer who thought binoculars had no place in serious astronomy - I gave him no quarter and told him to go over the hills and far away from me.
Now I am sick again with binocular fever, and after ten years gone, I still grab them first when heading out to observe. In this respect, my song remains the same always - it is a wanton song, of binocular love and appreciation. But then I dropped my binocular and it was trampled under foot and I truly learned at the moment what is and what should never be. Yes, it's true, I have a whole lotta love for two-eyed observing, and to those who disagree, I say your time is gonna come.

USN Binocular question: Mk 28
The Mk 28 (7x50) was made by Bausch & Lomb for the U.S. Navy. It is a heavy, substantial binocular. Mine has superb optics--as sharp as any binocular I've seen. But I would advise looking for ones in very good or better condition in the $100-$150 range. It should come with a heavy, rubberized USN/B&L case.

Mr. Gilmer,
I have great respect for your taste in old glass. In that regard, we are kindred spirits.
But, there's now another dimension that links us - I believe.

Well done, my friend. And I won't even try to respond with Waters, Gilmour, Mason, Barrett and Wright (rest their souls).

Thank you Darrell.
I am a simple man, with a few simple loves in my life.
1) great music
2) great glass
3) a good cigar
4) an occasional bourbon on the rocks
I just wish more vintage binoculars had long eye relief.
Regards and clear skies,
MikeG

Hello MikeG,
Some of the vintage binoculars, but not military models, had quite a bit of diopter compensation, making it possible for a user to remove his specs and use the binocular. Of course, for some of us, using a binocular that way might mean walking around relying on our own 20/400 vision, unless we put our specs back on, immediately after observing.
The B&L Mark 28, was the first binocular which I used for astronomy: seeing all four Galilean moons of Jupiter was quite a wonder! At one time, I had a Mark 21 and a Mark 28, the latter was purchased NIB in 1984, forty one years after its manufacture. I traded the Mark 21, which did not have polarizing filers for an Army model, the M16. I think that I paid $225 for Mark 28. The Mark 21 has very little eye relief, possibly because it was for aviation use and all flyers are supposed to have excellent vision. The Mark 16 was made by Nash-Kelvinator, which reminds me of the refrigerator in my childhood home.
I am sure that modern binoculars, like the best Fujinon and the ProStar, can be better optically, using more sophisticated eyepieces and much improved coatings.
Clear skies,
Arthur

Neat post, Arthur. Nice insight on early B&L units.
I, personally, do not find it offensive having to remove and replace the eyeglasses. Heck, I do it all night with my scopes, why not with the binocs, too? Shirt pockets, forehead and neck straps are all "retention" methods I've tried. I tend to gravitate toward the ole' shirt pocket.
But I definitely agree with Mike, there's precious little eye relief on the older Japanese binoculars. Nonetheless, they're still quite a bargain optically - compared to what you'd need to spend for equivalent modern glass.

Arthur,
My Mark 28s are my favorite binoculars; I use them more than any others I've owned in 60 some years. The B&L optics are top notch, if the interior surfaces are cleaned. The weight and lack of coatings don't bother me. One does, however, have to watch out for lens separation in these due to age and the cement used.

Hello DesertRefugee,
When binoculars are used for daytime use, switching from specs to binocular is tedious. I suspect that for astronomy, there is little walking around, while observing.
Clear skies,
Arthur

Unfortunately, that doesn't work if you have a astigmatism.

Hi OBX,
I have found, for me at least that, if one has enough diopter correction, running the correction up does help with my astigmatism. It really doesn't, but it does apparently. By that I mean this measure helps to minimize the effects of the eye condition.
In other words, over-correcting helps to minimize the effect of the actual astigmatic eye problem. Try it sometime.
Best regards,
Dave.

Interesting point, Dave. Actually, I'm lucky enough to have only very, very minor astigmatisms--but others should find your observation helpful.

I have astigmatism in the right eye, quite badly and the diopter does nothing to improve my condition. I do get a very strange effect with a graticule though. If I focus to one point , I can see the vertical lines, but if I readjust to a slightly different focal length I see the horizontal lines clearly.
This indeed proves I have astigmatsm, unable to focus in all planes at the same time.

Hi Simon S,
Good points. I use a copy of a chart to test my eyes sometimes. I guess I am fortunate that my eyes SEEM to remain about the same.
I got the copy of my chart from my eye doctor--the ones that they hold up in front of you or project. It is basically a number of (lines) going off at 30 degrees each. These will quickly determine if one is astigmatic or not, or, by how much. Good info.
Best regards,
Dave.

Have come across vintage bino's claiming extremely high power, sometimes over 100x, yet the EP's seem to have large eye lens diameters. Assume that this means they have internal barlows - by any chance are these easily removable?
Having bino's that can show Saturn's rings are one thing, but ...

Hi wfj,
This does not sound logical to me--we can't have it both ways! A large eye lens would indicate a large exit pupil. Some Japanese bincoculars, circa, 1960s, used an additional lens in the oculars to expand the field of view. Usually this was cemented onto one of the normal lens in the ocular.
I would suggest that you check out your source before investing any real money into something like that. Hope this helps some and good luck. This appears to be a contridiction in the description.
Best regards,
Dave.

Hi, Kenny-
Absolutely fascinating site! Had to bookmark it after watching the video for future perusing... which I most certainly will!
