I just bought an Astro labelled 76.2 x 1250 circle K scope. With it came two double circle V eyepieces. What I found of interest is that they both have APL stickers on them.

Some of you may know that the history of classic Japanese telescopes is a topic that piques my interest. I have been researching this for a long time and unfortunately seem to only be right back where I started (pretty much anyways). I have finaly done what I thought about doing years ago but was hopeing I would not have to as someone would come up with a solution to my problem, that being translation. I have contacted a professional interpreter who actually lives in Japan and it seems they may be willing to work with me, at my expense of course. I have a few documents written in Japanese that I am hopeing will help clear up some confusion surrounding this topic. If anybody has any documentation written in Japanese that you think will help I will send it along with what I have already. Please P.M. Thanks

Wow Greju, you're certainly taking this to town! I hope and trust that this major effort will show some rewards; I look forward to the outcome.

Here is a friend's scope...Diamond Z..I saw the Diamond Diamond Z-Zanzutsu post from STEVE MM's Red TASCO 6/29/10.
He is wondering what year the scope was sold by Sears.

Pic of my 20mm Swift Kellner, showing circle T mark. All of my Swift eyepieces have this mark. I assumed it was Towa, but apparently that's an assumption, the same as the AVA or AMA mark being Takahashi, not a fact.

I could be wrong but I do not believe that to be a Circle T logo. If it is it certainly is not like a majority of them.

Ah, you noticed that too Greju. I did wonder, as there appears to be a lot more space above the top bar than, as you say, the majority of them.
Any ideas on this one?

Wow, there has been quite a lot of activity since I last stopped in here. Max, your Royal, Circle K scope with Double V APL eyepiece is a real stumper.

I started this post a couple years ago after about 10 years of research, and 6 years of postings by knowledgeable folks here on CN. It amazes me that now 2 years post, there are still more questions and less answers. Greg, I literally have hundreds of Japanese catalogs and documents that I have translated and reviewed. All tell a story, most get contradicted later About the only Japanese companies that seem to have some consistency in "the story" are Nippon Kogaku and Goto Kogaku. Other than that, it was a crazy time for manfacturers in Japan in the 1950's-1980's.

Hi Steve,
Firstly, as it may be relevant, it isn't a Royal Astro, just an Astro, see here:
http://www.cloudynights.com/photopost/showphoto.php?photo=24971&password=&sort=7&thecat=3256
I'm intrigued by your research, do you intend to publish any of it? There's obviously a lot of interest, and even in just a crude cheap form, I'm sure it would be really appreciated.
Have you anything to add on the Swift/Takahashi saga? From what I've read here, it would appear that this rumour (?) started via an odd early connection? Is there any positive ID on the AVA/AMA mark?
Cheers
Max

I feel fairly confident AVA is Takahashi. There were several confirmations from sources during posts in 2008/2009. The main person who runs a website like CN in Japan also confirmed this on several occasions. Here is one post I found.. Swift There are more, just need to look around. Swift 831

Hi Steve,
I wish I read Japanese! The 'bought from friend' story needs a lot more detail to be convincing I feel; it certainly wouldn't hold up in a court of law, unless the cross-examination brought out much more detail. 'bought from Takahashi', what does that mean? I'm guessing it infers that Takahashi only sold their own make of scope; is this a fact? Can Mr Galakuma give more details I wonder? I find it extraordinary that the AVA/AMA whatever it is, mark, has not been positively identified. I'll do some more searching as you suggest, but I'm seriously beginning to think that this is a quagmire from which there's no escaping!
Cheers
Max

I pretty much trust Hiroki Shirakawa (Galakuma) and symbols. If he is not sure, he states such. Here is a post where there seems to be no doubt.

http://www.cloudynights.com/ubbarchive/showflat.php/Cat/0/Number/1956786/page/16/view/collapsed/sb/5/o/all/fpart/1

This post also reminded me that I have ads from Sky & Telescope that say "Takahashi by Swift". Not the same telescope as the 831, but no doubt a relationship between the two. Swift AVA and "infinity" as Takahashi seem likely, if not 100%. There are tons of other unknowns

Hi Steve,
Firstly and importantly I'd like to say there is no question of me not trusting Galakuma. He is a very polite and enormously helpful man. But I've learnt through research of various kinds, that each and every piece of information must be double checked, or you can get into the realms of assumption.
Right, having said that, let me tell you what I now have in my mind, and ask you to correct me. A company called Swift started out making astronomical telescopes in 1961 (?) For some reason they called their scopes Takahashi (existing optical company they chose to use?) During the next six years they manufactured at least three models numbered 838, 839 and 831 and sold them principally to foreign markets. For some reason unknown, in 1967 Swifts optical makers Takahashi decided to go their own way. Is this when 831's ceased to be made? I have to say I find the TS 65mm (the first Tak) to be interesting for two reasons. Firstly the length of the dew shield, and secondly it's colour. It would be easy to see how Tak carried this area of design over initially.
This is all of course ignoring the AMA/AVA device. From what I've gatheres so far this is unlikely to ever be solved; but, never say never!
Cheers
Max

Hi Max,

The deciphering of the symbols is quite difficult. I just read some of the other recent threads on the 831 subject and I see lots of questioning, wanting proof, etc. Unfortunately, after years of research on this subject I think we will always be left with conjecture.

It reminds me of the story of an old watch I have. The watch has been passed down for many generations in my family. The story goes that the watch was owned by american outlaw Jesse James in about 1867. The watch is from 1867. CD Peacock in Chicago verified they sold the watch in about 1867. Is there proof it was owned by Jesse James? Nope, just stories.

I like to think I have a cool watch from Jesse James. Those with 831's like to think they have a cool Takahashi telescope. Both may be true

Steve

PS, no disrespect was meant on the Galakuma comment, I think we all trust eachother but also look for "proof"

Hi Steve,
No disrespect taken. I do sometimes say stuff that I think afterwards I could have worded better!
Enjoy the watch, and in your secret moments.........

I have just bought a Towa 80mm f15, but its branded as "TOPIC PROFESSIONAL" It was Philj that confirmed it to be a Towa (circle T)i will be mounting it on a decent mount, selling the old mount and tripod along with the four 1" ep`s it came with,and fitting a crawmach 1 1/4 crayford

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???
