Hi folks, after a lot of search on web and a good amount of bucks, finally I have my Carl Zeiss Jena Telementor II tube on top of its T mount. What a wonderful scope! Heavy for a so little one. It is a masterpiece of optical and mechanics art! I was lucky to find a mint one, with a multicoated (purple) objective.
The only part that I have dispensed was its tripode. Too heavy for pay shipping from Germany by DHL, instead of I will use a Zeiss pier (Meniskas 180 pier) that I found in local a junkyard last year and is now under cleaning and waiting for painting work cause I am still looking for a epoxical grey paint that match the color of the T mount.
I got the Zeiss bug!

Pictures are required for all new equipment. It may be a rule, although an unadvertised one! 
Nice scope. Held one recently, and got to look through it. You are correct on both counts, heavyish and a great view.

Hi O,
A while back I also picked up a Telementor OTA but, it needed some TLC. It only had one sight and no dovetail or focus knob. Instead of trying to acquire the parts to bring it back to original I decided to make it more to my tastes as you can see in the image. The optics are excellent and the scope is fun to use.

And that is the one I looked through! Thanks again Sheldon. Hope I get to do it again.

Hi Doug, you are right! Pictures will be posted as soon my Canon P1 return from service (I need a new digital camera).
I will be proud to show it when OTA and its GEM get together again on topo of that, once junk, zeiss pier.
By the way, glass bead blasting is by far the best way to clear an old cast iron pier, after removing all plates and hardware, of course.

Hi Oliveira:
Congrats on the new "baby"! I just closed a deal on a Telementor II on a T-mount as well. I also got it with a Zeiss torret the accepts three 0.965 in / 24.5 mm EPs and one m44 threaded EP. It should hopefully arrive by mid next week - I can hardly wait! Now I have to try to find some 'inexpensive' Zeiss EPs to pop in the turret :-) (It's going to be a while before I can be looking at multi hundred $ Zeiss orthos :-o ) I'll post a photo too once it arrives...
If you come across any good Zeiss resources, please post them here, and I'll do likewise.
BTW, I've heard a couple different answers to this, but what is your understanding of what the difference is between a Telementor and a Telementor II? Thanks and enjoy!

Unless I am mistaken, the Telementor 1 has a helical focuser on the end of the tube, whereas the Telementor 2 has an "internal" focus system, with a rack and pinion inside the tube.

Hi Gary
You're correct, mostly, except that the internal focusing mechanism, which moves the objective rather than the eyepiece, is not a rack and pinion, but more like a giant crayford, riding on teflon pads. At least, that is how it works on my own 1989 Telemator (same OTA as a Telementor II). I also happen to have a early Telementor with the helical focuser and it is smoother than the internal one, but the internal focuser has more back focus and is better suited to adapting to modern 1.25" accesories.
Clear skies!

Hi Gary -
When is your web page going to be up and running again (Zeissnut) ?? Like Oliveira, I just got a Telementor II and the Zeiss bug that goes with it ;-) Ciao...

Hi folks.
According to my research we can classify the Zeiss 63/840 lineage into four models.
First was the "Schule Teleskop" with the venerable AS63/840 air spaced objective lens, a draw tube focuser and removable dew shield. It was manufactured from early 50s till early 60s. It was the same older AS63/840 refractor telescope, from late 20s, in a simplified version. Sometimes people call it "Telementor" too, but in fact the name was not used on it yet at that time.
Second was the Telementor (I), employing the C63/840 objective in a tube endowed with the very smoot 35mm helical focuser. Threaded extension focuser tubes are need to this model in order to accept eyepiece adapter, prism, and so on. Production ended by late 70s.
Third was the Telementor II and its variant, the finder equipped (and expensive) Telemator. These are better known because of its unique moving objective lens cell focussing system. No dew shield anymore, but a very elegant design. Tube back end has a internal threaded cap and all accessories employ standard 44x1mm threaded tubes or quick release adapters (tapered flange system, like in Zeiss microscopes).
All were made by Carl Zeiss Jena (DDR) and model II was also sold under Aus Jena brand, after a court decision took in a Zeiss AG (Oberkochen) law suit in mid 80s. At some time during its production run, objective lens become multicoated (deep purple).
The forth and unfortunately last Telementor model was the most beautiful one, made between 1991 and 1996 by the then already reunited Carl Zeiss. It was the same model II but with a white tube and the blue modern Zeiss logo. Some hardware (fastners) are stainless steel.
Some reports the existence of a pre-reunified Zeiss Telementor model II made under contract by Jena and sold by Carl Zeiss - West germany, but I was not able to corroborate that, may be Markus Ludes could give the last word about.
Regards for all

Sheldon,
Is that the Tasco clam you bought at NEAF this year? I have a Telementor one and i found that a 75mm Unitron clamshell works like it was meant for it. The scope is fantastic optically but sure is heavy, built like a tank. I purchased some adaptors from Alpine Astronomical so i can use 1.25" eyepieces. They were expensive but worth it.
--------------------

A small scope that gets used often is a better investment than a big scope that stays in the closet.
Unitrons, you spend more time looking at them than you do through them.

Ok guys, so is it really true that the Zeiss 60mm is 'all that" !! .... How would it compare to a good 60mm f/15 or f20? .... Like, would it blow it out of the water on planets??

I had a recent experience with my Telementor II, I was testing a 2.1mm eyepiece and was pleasantly surprised at how well the scope did. That's 400x and 160 power per inch. It did not lose sharpness, it only got dimmer.

Hi Olivera
In fact, there are several versions of the AS 63/840 as well. The very earliest version, made in 1949 to around mid-50'ies had a brass rack and pinion focuser and was mounted on the 1a mount. Later, the same OTA was offered on a simpler mount without drive. Then the OTA was redesigned to the helical focuser/drawtube version and the mount once again downgraded, now to an extremely simple version.
The scopes offered before WW2 were of 60mm aperture, the 63mm's only came after the war. The AS lens came out in 1926 and replaced the A design, which was of considerably longer f/ratio, f/17.5. The E achromats and B triplet apochromats were both offered up until WW2. The E, AS and B were all f/14 in the 60mm size, 60/850mm. They were freely interchangeable.
Clear skies!

That depends, of course, on just how good the lens is on the other scope... 
If the lens is superb, then no, it won't blow it out of the water. If the other 60mm f/15 is a standard run-of-the-mill China achromat, then yes, it will blow it away.
If I stop my 80/1200 Vixen down to a 60mm f/20, it has vastly better color correction than my Zeiss Telemator and arguably gives visibly better lunar-planetary performance, though the Telemator is a bit brighter.
Clear skies!

I have some really nice well corrected 60mm scopes but splitting hairs the Zeiss is still tops. But remeber it is not an apo, so don't expect a perfect scope. I have a close second with one of those "one out of ten optically great Unitrons" that are so hard to find. Unitron lovers don't get mad, most of the Unitrons are of good quality optically.  ( i don't want any hate mail)

Paint it Takahashi Green and nobody will know the difference. I have three of them, one was the sister of your Neaf buy. At least paint it white to match the porta mount and Zeiss. It looks like an inside out oreo cookie in your picture.

Brian,
I'll let the next owner worry about it. Maybe he'll like an inside out Oreo. It'll be going up pretty soon.

Just teasing, someone will be very lucky to get that cookie. It is a great combo as well i have a porta mount also.

Ok Ok ... well, of course....
I've got a wonderful 60mm Sears f/15 .. single knob metal focuser ...I'd guess circa 1958 or so ....
Throws a fantastic image of Jupiter and Moon...
So, I'd guess you're saying I wouldn't be 'blown away' then.
Ok, just wanted to know.
Thanks.

Nope, no blowing out of the water, but they are very sharp. I looked through one, and was impressed, but I'll keep my Carton 60mm f/16.7, thanks!
The Telementor sure was a beauty though, and it was indeed built like a tank. I think when you add in the fineness of the lens, along with the build quality, they are worth what they sell for.
