Not that I could find. Wondering if anyone recognized the combo of focus knobs, finder retention screws, red line on drawtube and lens cell? Happy to take more photos if needed.

jtii sticker style makes it late 70s or early 80s. if the letters are purple it is earlier, if black later.

Or maybe it was the predecessor to Tanzutsu but got a cease and desist from Volkswagen and had to reinvent themselves? What are the oldest and newest circle VV scopes known out there?

I found a mint Lumicon, Digital Quartz, Dual-Axis, drive corrector. It looks like it was never used. The cables still have their original twist ties, and the manual is dated 1986. It can run on 120VAC or 12VDC and outputs 120VAC variable frequency for RA and +/- DC for the DEC. It also has outputs for RA, DEC, map, and reticle LEDs, which I doubt I will use.

This was something I should have bought to go with the AP 706 mount, after I got it in 1985. But I already had a single-axis Kencor corrector that I was using with my C8. For the 706, I had a plan to wire up a separate paddle for the dec motor, which never happened. The plastic case for the motor got cracked at some point, and I took it off. Now that I have proper corrector, I've repaired it and ordered a new timing belt. The 706 doesn't have manual slow motion controls, so this is how it was meant to be used. At the time, AP was selling a dual-axis autoguider that would drive both axes.

 

Kind of cool that it is so close in age to the 706.

Wow, I used to have one of those! I used it with my old 6” Cave, to which I installed a Meade tangent arm dec drive. I sold that when I got my 10” Parks, which I adapted to run off of a Vista drive corrector. I still have that one and it still works.

I've always thought the scopes they are found on look like they are constructed the same and from around the same period. Which came first? shrug.gif

 

This whole subject of makers and such is never going to be completely understood.

 

If they are flat on the outside the focus knobs look like the ones used on the Penncrest and some other Towas.

As for Vixen having a budget line of scopes  it appears like they (and some others) worked with DK on the lower level entry stuff.

Like the Japanese binoculars with German sounding names, such as "Carl Wetzlar"?

Looks like the same color as my Sears blue tube. The packing in the drawtube came out of mine so that was it for that focuser.

Yup, exactly like those. And lens has a thin metal spacer ring and this textured lens cell that screws down.

At a local Goodwill found a Celestron Firstscope 80 (80/910) made by Vixen on an alt-az mount, nice finder, diagonal and eyepiece, just missing the tripod legs. Only $20 and all the glass is in great shape.

I bought the same scope about four months ago from a guy here in Phoenix for $50 that included the legs. It even has the little plastic triangular box with a Vixen logo on it. Included with it was a great 18 mm Celestron eyepiece from Japan and the TeleView 2.5 time Barlow lens. The optics on this vixen scope are fantastic and every bit equal to my Stellarview 80 mm scope. I’m always looking in Goodwill for finds like that, and you really got a good one.

The mount on this may be the most annoying of any scope I’ve encountered, but it looks cool.

 

It’s in pretty good shape but there is some edge separation on the objective.  If it ever gets bad, is it better to air space it or try to recement it?

Not worth your time.

P.M. me for disposal instructions.

Oh alright. My GM8 has some worm play, I guess I’ll have to send that along too.

 

I shimmed the tube so my 3” rings would fit and got about 5 minutes in before the clouds got heavy. Seeing was awful but I did get a couple of moments where the Cassini division popped into existence with my 5.5mm Meade UWA. No CA was visible at that magnification. I also got a very quick peak at Epsilon Lyrae with the same. For one brief moment both pairs were clean splits before the clouds washed them out.  I think I’m going to like this one.

 

it was rock solid on the Unistar but the focuser struggled in this orientation. I’m going to try figuring out a dovetail and balance arrangement that will allow me to reach zenith with my Nexstar 5 mount.

I got the 1930s scope on a stick from eBay, will be interesting to see how/if it works. Looks to be a 6" f/8.

I’m surprised literally nobody else bid.

I just found an Emil Bush 68mm f/12 from the 1890s or pre-1906. It comes with the tripod legs, case, and apparently everything else. Picking it up later this week!

I picked up what to me is a interesting one today. I first responded to the seller towards the end of last week, and was told that I was too late responding and a scheduled pickup was already pending. The seller then contacted me back a few days later and said the buyer never showed up last week for the set pickup appointment, and stopped communicating with her.

 

She said if I was still interested she would leave it outside on her patio today, and I could stop by to pick it up, and if I liked it after seeing it to leave behind $25 if I wanted to. I did pick it up and left $30 in a hidden location she directed me to. We never spoke in person, and just exchanged a hand full of text messages.

 

The scope is a 80x1200mm, and has two finder scopes and 4 independent counter weights. (One finder is a 40x450mm, and the other is a 6x with a 30mm objective lens. Both look original to the scope). It will definitely need some cleanup and work, but I think I should be able to get it all functioning. I will need to fashion some rings. Right now I just mounted it with some electrical tape for the photo. One is missing, and the other is cracked.

Can any one tell me more about it? I'm interested in knowing its approximate age and Japan maker?

The scope also came with a few accessories I just sorted through.

As the last poster said, a Dai Ichi Kogaku...DIK were OM's for a lot of other makers including Vixen & I cannot say what their overall quality was like for their own scopes - but my 80x1200 is a real performer! waytogo.gif

 

That said the mount is woefully inadequate for the ota & was probably meant for a shorter 60mm scope but pressed into service on the 80x1200 which is a real pity...despite there being worm & wheels on both RA & Dec axes.

 

I have the manual such as it is & not being a purest I swapped out the R&P focuser for a later crayford-style: I have taken planetary images through it as well as Lunar through the 40x450mm guidescope with very pleasing results - it gets a lot of admiring comments etc if I have it outside & set up in public places..! wink.gif

 

D-IKpage#1.jpg

 

D-IKpage#2.jpg

 

As well as the substitute crayford-style focuser I swapped in a RACI finder...another bizarre aspect is that the original tripod is sturdy (unlike the EQ mount lol.gif ) but is non-adjustable in height! I use a modern mount with it also btw.

It is very cool looking with the two finders and four counterweights. Too bad the shafts weren’t heftier.

Yes - we expect people to be "into" these old Japanese refractors here, but it is amazing how many people with no awareness of scopes who look at these long achros & make comments such as "Wow! - a real telescope!" :lol:

 

Yes, those mounts were a real problem Terra - & the first tripod I've had that cannot be adjusted in height...not counting the 19th Century surveyor's ones that came my way after a clean-out at the museum!

This is a really nice telescope. I also like the four counterweights. If the mount is undersized they are probably needed but they look great. The only other telescope in which I have seen two finders with the smaller one mounted on the focuser base is the Sears (AO) 6336 76mm f/16 refractor. What a great find. Enjoy!!

Apologies...posted before lol.gif - but with an old iphone up to the ep with Saturn only about 15 degrees above the horizon & with terrible atmospheric distortion at that elevation (ignoring the terrible seeing also) here is a little snippet of the feed from the D-IK 80x1200mm plus the resulting image.

That is what i call fast river seeing. Looks like fast moving water.  7 more years for Saturn to get higher. That is what it looks like to me also and i am in FL.
