Over the years, I think this thread has gone through the washer and come out a different color. Even so, I thought I would add a new eyepiece/symbol to the thread.

Anyone care to guess what telescope this BOL Japan eyepiece goes to???




Bushnell Optical Laboratories?

Correct. It is the 80-160x eyepiece from a 1972 Questar 3.5. The 40-80x eyepiece is not marked BOL. I find it interesting that Questar was using the same BOL manufacturer as many of our classic scopes.

My late 60's Questar had that same EP I believe.

Now, a couple impostors. First Circle W. Anyone know where this comes from?




I went through this entire thread, albeit rather quickly, and could not find an answer.....what is the Circle W?

Thanks,

I just picked up a 1984 Swift 60/800 Aerolite and it has a KD on the underside of the focuser on the rack plate. I used to know this brand but have forgotten, any ideas? It has some Cartonesque features to it but it also has more plastic than I would have hoped for. It is a model 863.

I believe that is Kenko. Is it like this KD?

I believe KD is Koyu.....KD labeled parts and eyepieces can be found on early Vixen products and Koyu was the predecessor company to Vixen.

I have a couple of .965 Celestron branded orthos with a similar KD logo.

If you check out this post: Crescent "KD" on CN You'll see the same mark on a Crescent in my collection. I've been trying to track that down for almost a year.

Good to know that it may have some early Vixen ancestry.

And the silver sticker on yours is identical in shape and font color to Vixen labeled scopes. I also suspect it's not a D in what we call KD for a variety of reasons but some kind of stylized symbol around the K that we are interpreting as a D. However I still refer to it as KD in posts because everyone is familiar with that term. And I could be wrong....

I had an old 60mm f=900mm refractor once with the KD logo on it. The whole scope was pretty much made of plastic, including the tube but the optics were excellent. I gifted it to a friend and he has been enjoying it ever since.

I could never figure out what an "Astoronomical" telescope was though.

Hmmm....that woud suggest that Kanko is related to the KD symbol.

Funny that they blocked out the spelling error.

I found an old photo of a Celestron .965 accessory kit that came with a C90 I once purchased. It contained an 18mm Kellner (KD), diagonal, and 2x Barlow.
