A few weeks ago I bought a 3" fl:910 refractor.On the focusser is standing O.K.K.K astronomical telescope japan,
and a letter K in a tiny circle.The included original manual
mentioned the 3" fl:1250 refractor and several 2.4" refractors with focal lengths of 710,910 and 1200mm.
The name Kyanon Kamara Kompany was used from 1947 until 1969.The optics of mine 3" are very good and comparable with
the 3" Unitron/Polarex.
A 3" fl:1250 refractor was recently sold for $175 and all
original and complete with the wooden case ( in the U.K ).
It was marked as a rare telescope and I also had never before heared of a Canon telescope.It is likely that not many of them were imported in the U.S and Europe.

The telescope I have is a Panorama 60 x 1200 mm refractor.
It is marked O.K.K.K. Astronomical Telescope D=60 F=1200 Japan K.
Last weekend I set it up for the first time. Being summer in the southern hemisphere (Lima, Peru Lat 12º S) the sky was clear enough to see the rings of Saturn with the 20mm eypiece. I could not manage to see them with the 6mm.
Believing the equatorial mount had to be level befor setting the polar axis, I have added a 1mm steel plate between the base and the rotating mount, on top of which I put a small round level. See attached photo.

I found a gentleman who also owns this telescope and has the original manual that came with it indicating it is Vixen made. That manual is on the way to me. So, after obtaining information from Company 7 indicating Vixen was Koyu Co, Ltd before they changed the name, I deduced Circle K=Koyu=Vixen.
Now, I come across this thread. Very interesting. Does someone have some information indicating Circle K is Kyanon Kymera? And, if so, is Kyanon Kymera known today as Canon?
I collect vintage refractors and have never seen the Circle K before having acquired about 50 vintage refractors and hundreds of eyepieces. Now, today, a little 40mm arrives with Circle K. Matches the 76mm nicely

For this reason I would say that the Panorama telescope is probably not made by Canon.

For about thirty years now I have owned a 3" refractor about which I have been unable to find a single snippet of information and had pretty much given up!
The focuser bears the markings:-
D = 76.2 F = 910
Japan followed by a K in a small circle
The scope came with a single folded sheet manual, which had a table on the back listing other scopes in the series, their specifications and product numbers.
According to this table mine is an OKT-118
The others listed were:-
OKT-122 specification D = 76.2 F = 1250
OKT-117 specification D = 60 F = 910
OKT-119 specification D = 60 F = 710
OKT-121 specification D = 60 F = 1200
OKT-123 specification D = 60 F = 710
The manual has absolutely no information regarding the manufacturer at all and is very poorly translated presumably from Japanese
I have no idea about any of the others, but mine yields near perfect diffraction patterns on a star test and CA only really becomes evident once you exceed the 50x per inch limit… and it is still my favourite scope for white light observation of the sun - obviously properly filtered!

You unscrew the eyepiece adaptor from the focus tube. The ring on the end of the bar then slides onto the focus tube. You can then refit the eyepiece adaptor and lock the bar in place with a thumbscrew, the projection plate then fits onto the bar...
Yes, it came in a nice wooden case with foam inserts. A diagonal, 3 eyepieces, poro prism,barlow and 2 filters. There is a square metal plate with an arm for attachement to where i dont know.Maybe a solar projection although only about 6x6inches. Still waiting for clear skies to test it out
Maybe a picture is easier
Sorry it's a bit dark, but I was more interested in the total eclipse which had just started
Incidentally, the little white spot below and to the right of the Sun is the reflection of the eyepiece on the projection plate...
