Is this a Circle-T eyepiece?

[bendiddley]

Received this with some kit I bought recently. Am I right in assuming it's a Circle-T eyepiece?

Yes it certainly looks like a Circle-T orthoscopic eyepiece. Telescope House sourced some from the manufacturer in Japan a few years back in enough volume to have their name engraved on them.

Looks in nice condition. Originally it would have had a small sticker on showing the Circle-T logo and the country of origin but these did have the habit of falling off after a while.

Thanks John, very helpful! Yes it's in great nick.

Nice planetary EP's they are. Sure a little short on eye-relief, but usually very sharp!  Rob

Definitely worth keeping, I use mine a lot.

I always think of them as Tani eyepieces first since he did all the assembly.

It looks unused.

I binoview with a pair of these albeit UO, and they are about as sharp as you will get.

Nice one @bendiddley 

Apologies for the poor images, but here is my 6mm & 12.5mm Circle-T Ortho's...

 

...and a 0.965" Ortho and a 1.25" adaptor.
