Are there any orthos on the market now? Or did they vanish?

We're still waiting for the Baader Classic Orthos. Not too bad. It's only been a year since they were announced.

According to the TMB website, the TMB Planetaries have 6 elements.

TMB Optical Planetary Type II

Abbe Orthos have 4 elements. A Barlowed ortho? :shrug: I can't find a diagram showing the design of the TMBs.

Opt has the 25 and 18 Kasai-same as BGOs-in stock and the others on order. I would go for those over the BCO and day. David

The Kasai orthos are having availability problems according to another post. The KK or University Orthos seem to be having the same problem according to Kokusai Kohki's website. In fact KK website says get them NOW while you can.

I suspect in the next couple months the only orthos you can buy will be used ones in the classifieds.

I don't like the sound of that at all! I was planning to get a 9 Kasai when they came in. David

David, I hope it's not true either. I was planning on buying some Kasai HC Ortho pairs for my binoviewer from Agena Astro when they got them in stock. I guess I should have gotten them from Hutech when they first came out.

Mannish from Agena sometimes posts here, maybe he can give us an idea what is going on.

I was wrong on the Fls of the HC Kasai's avalable at OPT. It's 12 and 18 not 18 and 25. In fact there isn't a 25 and 18 is the longest FL. David

Based on what I am reading at KK's and UO's website, there are problems with production and no guarantee that they will be available after current supplies are sold. Lets just say, if you want one, you better order one now.

Lack of available lens makers had been cited by both sources. IIRC, the tsunami destroyed the original suppliers in the Sendai area for the BGO/UO HD/Kasai orthos and the one guy supplying lenses for the KK/circle T orthos had either gotten too old to continue work or passed away.

And possibly other manufacturers are asking for quantities and prices that make the whole thing unrealistic.
Japan has become an expensive production country and the high Yen does not help either...

There are still the chinese orthos on the market and maybe they will be the only ones left?

best regards

You are right about buying while you can.

I'm sorry to say that the 6mm-7mm-9mm KK Circle-T's are now out of production. It truly is the end of an era.

We will have to see what the future holds for us.

If the 9mm Kasai HC never makes it into the realm of reality maybe I should get the 18 that has the big plus of existing. At $119 the price isn't exactly budget busting. OPT has the 18 and the 12. I can barlow the 18 for lunar-planetary powers in my cats and refractor. It would be usable a lot more often than the 9 and I can even get a 12 out of the 18 with my 1.5X Siebert barlow. The 18's extra ER is also a big plus for me. David

Re the Volcano Tops, University Optics still caries the same ones they have for a few decades. They are about $84 apc.
You can tell which size is not available by clicking on the drop down menu. Went there yesterday, no 25mm. Last week the 25mm was there, but no 6mm. Etc.
I had a couple emails back and forth with them last month.
Reasons i was told for the ortho "shortage"

There previous flat top HD line was dropped due to the owner of its manufacturer dying. It was a very small operation. I think this may be also the explanation for the long wait of the "new Baaders", and other flat tops of Japanese origin.

Also, the "turbulence" from the storm/reactor problems is still being felt i guess in some quarter.

Snap those VTs up while they are still there si what I would do - and in fact I did :) I kind of saw this one coming about a year ago and decided to just get on with it.

I daresay the BGOs will appear 2nd hand occasionally - one just did on Astro Buy and Sell (UK)

I sold my BGO 5mm not long ago. I could not justify keeping it after I bought a Pentax XO 5.1.

I have the BGO 6, 7, two 9, 12.5 and two 18. I also have a UO VT 4mm and 25mm, two LOMO 20mm from Belarus, the entire series of Faworski orthos (as far as I know), and a Vixen 2" 40mm.

All my other UO VTs and clones have been sold except for an Edscorp volcano top 18mm (equivalent to UO VT). Anyone PM me if interested.

I think I'll keep the rest!

Mike

The gentleman who makes the KK volcano top Orthoscopics is retiring. He is now in his late 80's. Just imagine how he feels for having brought excellent eyepieces to the masses for so long. He must feel REAL good.
