Ok, I have no idea what this thing is. The seller has no idea what it is. Now I am really curious. The binoviewer end looks interesting and looks like it could be adapted for use as a binoviewer with a standard telescope. The stackable lenses are curious as well. Anyone have any idea what this thing is? And could the binoview end be used with a scope?

I've only seen one similar set...back around 1971. The set I looked thru had one objective, and the focus was battery operated. I do not remember any of the details, but the next time I see the man that owned them I will ask about them.

I have a couple of 'em here, though without the multiple objective stacks. They are an interesting novelty.

But what exactly does it do? Or what is it used for?

And, what interests me, is the binoviewer unit. Is it a standard beam splitter? If so, it's just a matter of mating it to a 1.25" or 2" visual back and playing with the focus range.

I would imagine the multiple objective stacks would start eating up light transmission at some point, resulting in a very dim image, especially after passing through the beam splitter.

I might get impulsive (and bid) if I thought there was some use for this thing, such as a binoviewer.

Google search turns up these are Leica compatable screw mount lenses. Zeika was a contraction of Ziess and Leica and made in Japan to fool consumers that it was German optics.

Oh No not an electric zoom ...
I had hoped I would never see these again.. :bawling:
These "things" do work for daytime viewing but are basicly worthless for anything more...
If you buy them "TNR" can align the prisms if they get knocked out of alignment but they will need several to scavange for parts if something go's wrong with the zoom / focusing...

The bino part of it uses too much backfocus to be used on almost any telescope.. { Save Your Money }

That is the $64,000 answer to the $64 question. ;)

So this thing is interesting and strange, but not very useful for astronomy.

Thanks for the info folks!

Interesting find, Mike. :imawake:

The center objective appears to be a camera. :shrug:

No, not really after looking at the photos a 2nd time. :smirk:

It looks like what the Aliens used on Kartman at South Park for his probing! :shocked: :shocked: :shocked:

If I had money laying around to risk, I would bid on it just for the novelty of it. It's strange. It's not very common. It has vintage Japanese-made optics. It has a binoviewer. It can be assembled in various configurations like an optical erector set of sorts. :)

But $100+ is a little much for what would amount to a nifty toy for me. If it had some legitimate astronomical use, then maybe......

Zeika. That is funny. The illegitimate child of Mr. Zeiss and Mrs. Leica.
