Do you see your reflection in a TOA 130? Does no reflection mean the scope is better?

The Tak will have awesome coatings too.

p.s. If you change the camera angle on the TEC lens and light it right, you can see a full reflection.

Greg N - "Leaving aside the aperture, cost, and performance issues, the main advantage of Takahashi is that it is not a one-man shop. The corporation appears to have continuity. A one-man shop is susceptible to the vagaries of health, retirement, and all sorts of things..."

I'm not so sure about that but I could be wrong (if anybody spots any errors in this post please correct me because I'd like to know!). At Astro-Physics, Roland finishes each and every lens. At TEC, I believe there are two or three opticians working for Yuri. At Takahashi, fabricating lenses certainly used to be - and I believe still is - contracted out to a Canon subsidiary (the same one that makes the lenses for the more up-market Vixen scopes). So Tak's continuity is partly at the whim of an outside supplier. I agree that all three companies make great products and a well looked after scope from any of them should last generations.

The elements for the FS-60C and Sky-90 come from Optron division of Canon.

The glass for the lens blanks on the TOA, TSA are purchased from Ohara in Sagamihara, a suburb of Tokyo.

Thank you for mentioning Optron, I couldn't remember the company's name. The blanks for the TOA and TSA scopes might come from Ohara (who supply many refractor makers) but who is doing the final polishing and figuring? Or are you telling me that these processes have moved in-house to Takahashi now?

Thanks in advance!

Takahashi grinds and polishes these lens blanks from Ohara.

...so this is also a battle of "made in Japan" v "made in USA"...

Regardless, we can be sure of one thing - both excellent, gorgeous telescopes made by people with funny accents.

"Just to put this to rest, OPT does in fact have a TEC 140 in stock. I placed my hands on the TEC 140 Saturday afternoon. It is set up on their showroom floor."

Not a selling point for me! Too many people with thier grubby mitts on it:)

And if you get the camera angle right on a C14 corrector plate, you get no reflection. (well the dowel used for collimation has a reflection but it doesn't look like there's glass there)

I also confirm a TEC 140 @ OPT. Since I'm local, I'd have no objection to purchasing a floor model, as I'd have my hands AND eyes all over it before I bought it. It is a looker...I have a TOA 130 and like it very much!! The TEC is lighter, and I am visual only. I'd have no problem selling my TOA and replace it with a TEC 140 if I get any weaker with old age .

Wow, now that Clark is dead, I guess they had better scrap the Lick refractor.

It's going to be a lot more difficult to get a Clark serviced than a Tak these days. And they ARE trying to scrap the Lick.

This is an elementary point. When TMB went he took TMB with him. Tak may or may not have Canon do its lenses, if it does, more power to them, because Canon is one of the strongest names in the world. But Tak has been around, if memory serves, since the 1930s.

A lot of the big name shops like AP and Televue won't work on other brand refractors, even though they have the know-how. So if you have an out of date refractor you have significant problems.

But yeah sure I'd be a Tec or an AP. (except I got a good price on a Tak)

I'm a bit confused. Does OPT indeed now carry Yuri's products or was this a trade-in sitting on the floor? My understanding is that only Anacortes was the "outside" dealer for TEC here in America. Anyway, most folks deal direct with Yuri. It just feels more comfortable. If there are delays you get the exact info immediately.

Thomas was a designer. His designs persist after his untimely death. The LZOS/APM triplets are TMB-designed and still available. The TMB Optical scopes, likewise, remain available and manufactured to his designs. To my knowledge, Thomas never had anything to do with execution, fabrication or manufacturing at either company, so I'm not sure what you meant by "he took TMB with him".

Jim

My TEC 140 is the best scope that I have used so far for photography.

Here's those lesser TEC 5-layer coatings. The 7 layer coatings must be really something. My flash is directly pointed at them.




Hey, I will trade you my superior 7 layer coated TEC 140 for your inferior 5 layer TEC 200! Straight across!

When I saw the TEC 140 at OPT, I asked Mike (behind the counter) if it was a trade-in. He said no, they (OPT) had started to carry TEC. It had the lens cover on, and I didn't attempt to remove it, but I lusted after the FT focuser!!

Yes, OPT carries TEC scopes now. I just find it hard to believe they actually have one in stock. Good thing they don't have a 180FL listed as "In Stock". I'd take that over any of the afore mentioned scopes in a heartbeat! As well as others not mentioned.

Originally a "real TMB" was considered to be a scope that was purchased directly from him. It involved a lot of "special touches" and assurance that it was as close to perfect as possible.

He polished the tubes to an automotive finish, he selected the LZOS optics, tested them on his double-pass auto-collimator, aligned and tuned the focusers, aligned/collomated the optics and finished with a star test under the night sky. He would not sell a scope that he wasn't willing to keep as his own.

He was not involved in the fabrication but if a scope was sold as a TMB he personally made sure that it would live up to his expectations.

You could buy the same scope from APM but it would be without any involvement from Thomas other than the design of the optic.
