I'm involved in an estate sale with gobs of astro-items from a well-known observer--and his son--here in The SF Bay Area.

 

There are a couple of giant binoculars with no name, or inscriptions anywhere on them. One has 6" objectives the other 5.5", but of a shorter focal length. We have not tested them for collimation yet, or anything else, for that matter. Can't find a suitable mount in this storage locker for them, either.

 

I'm including a few pix here in hope that you bino-observers might give me a clue as to what they are, and maybe what they are worth, if they are in good to excellent shape as they appear to be. Only the 6" is pictured--and it weighs a ton! The pic of my buddy Dan shows the boxes they are in, for perspective.

 

Thanks!

I'm curious what you will find out. Looks like a home-made instrument to me.

It's possible the observer may have belonged to a club, post about astronomy on CN or other place or maybe even wrote books. He or she likely shared his binocular passion with someone or a lot of people. So that would involve tacking down people who knew her, him, them...

I'm unclear if the observer and his son are both deceased?

The pictures are a bit dark. Putting something next to it for a size comparison in a picture, like a soda can, helps.

Yes this, find his club or observing buddies. They'll know.  Or his CN account or any other astro forums or mailing lists out there.

 

I once bought astronomy stuff from the sons of a deceased man. I did manage to track down his club and did get some information.

Whatever they are, they look professionally made. Definitely an awesome find! Even if it turns out the Objectives are from a Copying machine, they can be replaced, the stuff in the back is the difficult part grin.gif

Haul one out and pop on a table and see what the view looks like, probably achromatic, but could give a nice rich field. So update us.

To answer a few questions:

 

These binoculars are from Bill and Mark Cherrington. Noted SF Bay Area observers; long time frequenters of the Texas Star Party, RTMC, and others. Bill made one of the largest homemade Dobs at the time (under John Dobson's tutelage) maybe 45-50 years ago. He ground and figured this 16" mirror himself. I remember star-testing it myself 30 years ago and it was perfect. He named it "Evergreen" and hauled it to aforementioned star parties more than once. Bill had a stroke last year and is in a rest home near his daughter and son-in-law in Washington state. Also last year, Mark, Bill's son, died of a heart attack. He was only 61.

 

Mark was more the 'amateur telescope collector' than his dad. It took a while before Bill recalled these binoculars. This is what I have received from his son-in-law:

"We got more information about the binoculars.  Apparently, they are from a European military organization and would normally be used on a military ship or outpost.

Bill said that Mark purchased them, and believes that he paid about $5000 for the pair.  He said that he’d be happy to get around $500 for each of them.  Looking at other similarly sized binoculars it seems that it would be a fair price."

 

Both are already sold to local, interested parties. Even untested, $500 apiece is quite a bargain!

Thanks, would be great to have a lm observing report from the new owners.

If Google translate got this right a Russian made 30x180 doublet with 73 degree AFOV eyepieces at a 30 degree angle and 29kg weight. There also is a monocular of this size mentioned on page 3.

There are 2 versions, 140 and 180, as mentioned in the thread.

This comment indicates there were 100 of these made by KOMZ as a special order for USD 2k per piece and all went abroad.

A 7" f/4.1 Achromat is not that promising at all ...

Fixed eyepieces? Huuhhh

 

But as a decoration piece in the office quite impressive for sure ;-)

They had some smaller ones that looked like modern Flak binoculars. Angled 10x80 would be quite useful if someone could design some.
