Ahh that is you! I wondered. Your on a very slippery slope now!
You need a Audubon or two to become a true Japanese binocular collector though.


I had one of the earlier Audubons Simon. Excellent glass for a variety of obvious reasons. My issue with that particular version though was the eyecup design. I need to completely remove the metal eyecups in order to see the full field of view on most of these models. This particular Audubon had the twist-up metal eyecups and I could not find a way to easily remove them. They found a good home now though with a fellow BF member. I believe his most recent comment on them was something along the lines of "...being buried with them.".

I just sold reluctantly a very nice Japan made earlier one piece bodied Pentax 8x40 porro, lovely binocular with the american style body, the reason?,short eye relief, even with the eyecups folded down I lost most of the view if I left my glasses on, I had bought a couple of years back a Nikon Action Ex in the same size as the Pentax and found it to be the one I reach for when needing a 8x40 glass, Dave.

Did they have the orange coatings? Later models reverted to normal coatings. I quite like them both but sadly the orange coating models performed better but with a green tinge, although subtle was off putting.

Mine had the normal coatings with a wide angle view, however like most wide angle models the edge of view got a bit soft, Dave.

Does anybody know if these binoculars are suitable for stargazing ?
They should be from the fifthies and have some sort of coatings.
Auction ends in 9 minutes :O)

I watched the launch of Apollo 11 in 1969 with a borrowed Lieberman & Gortz 35x60. They had the extra benefit of being able to see the launch pad with the left side of the binocular and at the same time, with the right side I was able to see bikini babes on the beach!
Put another way, the collimation error was not measured in degrees, minutes or seconds but in compass directions.
The chance of those being even remotely collimated would be pretty slim.

Thanks for the kind welcome Bill!
I would love to learn to clean/service some of the pairs I have picked up over the years but collimation just downright terrifies me! I think listening to you guys here may be what I need to overcome my "phobia". Is there a good book on the subject you could recommend?


Yes, The Navy's OM3 & 2. There are many devices and techniques. Many, though I refuse to relate them to TRUE collimation, will serve ONE observer JUST FINE.

Send me your real email address, and I will send you more info. < wjc 1111 (at sign) hotmail dot com >

Cheers, :jump:

No, no good at all.
I was on Ebay.uk, but they really looked quite miserable, and the eye pieces was missing.
I wouldn`t mind look at the bikini girls, but a look at the moon at the same time would make me sick.
I better save my money for a Zeiss 15x50 Simon?

There is an auction site in Switzerland, called: RICARDO:CH
they have quite many german and swiss binoculars for auction there.
I just bought a Kern/Leica armee 8x30 there.
You just need to sigh up, and a entrance code will be sent to your residence,and you are free to go.

Am I making a fool of myself? you know about this place already? :O¤
If so, forgive me

I would go for a maximum of 10X in a 50 mm objective. Read up about exit pupil sizes. Try a Jenoptem 10x50 as a good start to 50mm binoculars in the classic range. Look for a t3m coated version.

Thank you for your valuable information Simon, but can I please ask you one more?
tomorrow on Ebay.de
there will be a Steiner marine fernglas 15x80 for sale at 11:25:38 sunday
could this be useful for astronomy on lower level also?

I cant really coment as I do not know this binocular. A good 15x50 would be great though but a tripod would be needed.

Have you read the very long, locked, then unlocked, then again locked , thread about this topic which developed last year? It must have set a record for thread length. I contributed a lot to it and to its sequels and predecessors, including a low-cost projection laser aligner for binoculars.

You should wish to make the optical axes of each barrel parallel to each other and to the hinge axis. In this condition, the optical axes will be parallel to each other at any interpupillary distance (IPD). If the optical axes are parallel at one IPD, presumably set by you at your personal IPD, without being parallel to the hinge , then they are parallel at only that IPD. This has been called "conditional alignment".

So-called "collimation" has several meanings, depending upon the context. For binoculars, it would be better to call it unconditional alignment, or 3-way parallelism, or 3-axis parallelism, because:

Collimation of a monocular Newtonian telescope, or a monocular refractor or a catadioptric such as a Cass. or a Schmidt-Cass. has been made possible by the Cheshire eyepiece, the sight tube, and recent laser collimators. Here, collimation means proper alignment of the components of the monocular instrument.


Has anyone heard of attempts to collimate the components of one side of a binocular, before conditionally, or unconditionally ( so called "collimating") aligning that barrel to the other barrel?

If a 2-hinge Porro II instrument such as the Nikon 20 x 120,or similar WW II Japanese military binoculars, or the Fuji 25 x 150 or 15 x 80, or some of the straight view Kowa 20 x 120, or the prewar Zeiss mounted binocular telescopes, or the postwar DDR Zeiss Jena versions, or the Chinese copies/near copies have been disassembled in the prism region without retention of the (hopefully) factory correct position of the prisms , it is a good idea to attempt to collimate the affected barrel within itself,and to its own IPD change bearing axis, before attempting alignment of that telescope to its mate on the other side of the body.

A long reach comparator , such as the JTII rhomboidal or something similar,with or without an attached auxiliary telescope, to peek round the prism drum and body anywhere in a large angular swing , even 360 deg., is a big help in attaining an approximation to alignment of one barrel to its own rotating IPD change axis. At the same time, an attempt should be made to keep that telescope optically collimated. One thus gets an idea of the problems confronting the designers, production personnel, the factory assemblers, and ,one hopes, repair people who may eventually have a role in the life of a binocular telescope , be it single hinge bearing, or double hinge bearing.

Once a monocular half of a binocular telescope has been collimated, it is a very difficult mechanical/opto-mechanical proposition to attempt to exactly align the optical axis of a similarly collimated scope to the first one, without departing from collimation within one or both of the telescopes .

Therefore, it is a misnomer to call 3- axis alignment of a binocular "collimation". Though the collimation departures within each telescope may be small in the very best grade of binocular instruments, a departure from collimation within one or both telescopes of the binocular, even if one or both were originally collimated, is inevitably a result of 3-axis parallelism achievement. The difference may or may not be negligible.

I didn`t get the Sreiner 15x80 on Ebay.de.
The guy selling the bin had another cover up identity, who popped up the price to extremes.
is this legal?
I think it`s unfair business

It happens. No it's not legal but you need to prove the same person is upping the bids and then inform ebay.
I would not discuss it further on CN as moderators may well intervene.
Look for another pair Alan, I know how you feel though.

Thanks Gordon. I found the thread on the mk.V collimator and gave it a quick scan,what has always confused me about alignment/collimation has been aligning the optical axis with the mechanical axis, now it makes sense.Good stuff!

I tried a Steiner 15 x 80 during daylight and it was a good performer, but the guy who had it reckoned that it didn't show much more than a Fuji 16 x 70 at night. The Steiner was difficult to hand-hold due to the fattish barrels and length/weight. I eventually bought the Fuji and haven't been disappointed.

After almost two thousand posts to the old "Vintage and Classic Binoculars discussions" thread it is time to start a new one before the forum software has a heart attack! :)

To kick things off here are a couple of pictures of my Swift Audubon 804ED (8.5x44). Not a vintage binocular (mine was manufactured in 1996) but a Swift collector might call it a classic. Very sharp on axis and a decently wide field of view (~8.2°) too.


Richard McC, I used my Audubon ED 8.5 x 44's this weekend and noticed that the right-hand top-plate is slightly different to yours: where yours says 'SWIFT', mine has the same red 'ED' logo that's lower down on yours, and 'SWIFT' is nowhere to be seen (it only appears on the left-hand top-plate). Everything else is the same. My serial number is 940466.


Yours fast becoming a Swift geek,

Malc

Malc, I've seen pictures of other Swift 804ED binoculars with markings like yours, s.g., in this PDF from the "Historical Review of Swift 804 Audubon Binoculars" thread on BirdForum. I believe the differences are purely cosmetic.

Just found this Nikon on ebay, looks like a Pentax Marine / B&L M3! Never seen this model before, a baby tropical maybe?

That looks sweet simon 8.5 degrees from a 6x30,nice! if its as good as the tropical it could be the best 6x30 ever made. I have never seen one before and if I had the spare funds I would be all over it! Go on buy it. so I don't have to.
