Terra, 

Your T-1 looks great!  I especially like the hardwood Tripod Tray.  Did you build that and the accessory box on it?  Is is oak?

The blue metal try, on mine, is functional but lacks any "warmth", while yours is functional as well as beautiful.  If you have any specs or drawings I would enjoy building one of those for my T-2 also.

BTW, Cory Suddarth cleaned and colllimated a few of my older binos and vintage zoom eyepiece and they all worked "like -new" when returned.  

Clear skies,

Hi George,

 

Thank you. I have the leather spreader straps but I put them away as I like the rigidity that a locking tray gives a tripod much more. I didn’t make it myself. It was made for me by a good friend who is a cabinet maker and master woodworker several years ago. The wood is baltic birch and it has three coats of Minwax polyurethane on it. The locking knobs came from Lowes. I don’t have any drawings but its an equilateral triangle approximately 17” on a side (vertex to vertex) with the vertices cut off. The box was finished the same way and is lined with green felt. It came unfinished from Michael’s Crafts. I polyurethaned it as well and lined it. I wanted them to match the lovely light wood of the Zeiss tripod as best I could.

Well, I have one and... Honestly, they're not all that good, compared to modern eyepieces. A 40 mm 1.25" plössl is a vast improvement and a 42 mm Superview Erfle is in another league entirely. 

 

The turret is another matter. Very nicely made. The prism in mine is not as good as the prism in my Baader T2 amici prism diagonal, though, but I never noticed that, until I did a comparison.

I actually realized there are two 40-H eyepieces-the conical one and the tubular one with bevel. Are they similar to each other?

Terra,

Thank you for the info. It really finishes off that classic telescope nicely!   Baltic birch plywood is what Tom Noe built my 10 inch Teleport with. Excellent strength and great finish for cabinet. Tough material to find lately.  

Clear skies and stay well.

Here's a Zeiss accessory you don't see all too often: The solar projection screen for the Telementor/Telemator. CN absolutely refuses to show the picture the right side up, so you'll have to imagine that.

It comes up on ebay time to time, but as other jenas accesories, they're rare.

Thank you.  Trouble is purchasing from that European based website.  Don't know if they will ship to the USA.

Also can that site be translated to English?

George,

Both of them were sold, in 2017 and 2018 on ebay. I just pointed out that it may be possible to find it in the market someday.

If you look out often time to time it comes with telementor package.

 

I saw this one, sold on ebay as well (no info on year)

Carl-Zeiss-Jena-Refraktor-Teleskop-Telem

Also this telementor package (unsold in 2019):

https://picclick.de/...3564265605.html

Carl-Zeiss-Jena-Telementor-Teleskop-Refr

I would try contacting the vendor, maybe he still got it (https://www.ebay.de/...=p2047675.l2559)

 

And another thing, the website is not in german, but it archives the past ads from german.de ebay.

The price is expensive on that one!

 

And that AS lens..I'm not sure if it's the picture but it might be moldy?

Good find though, one was up in classifieds earlier this month.

That’s awesome Allan. I’d love to swap my 8” Tec for the Zeiss just because it’s a Zeiss and regardless the 1” downsize.

That is a nice scope Allan! and interesting specs.  I must take a look on a catalogue of Zeiss question.gif . I am not fully aware of all the models CZJ and Zeiss West offered in the past.

     Thank you guys; -- I'm not gonna swap my Meniscas any time soon... wink.gif (but I'll probably pass in on for sale in a couple of years down the road, when it gets too cumbersome to handle, in my late 70'ies...).

 

Carlos:

    The Meniscas 180/1800 was produced by Zeiss Jena in the 1990'ies for advanced amateurs, schools and universities. It's a compact Maksutov catadioptric with zerodur glass-ceramic main mirror and a small secondary, yielding a bright wide-field image with small field curvature.The resolution is 0.64" and v_mag 13.7m.

 

     The Meniscas has a wonderful smooth precise internal focusing mechanism, and the backend can be configured very securely and flexibly for all sorts of visual and photographic purposes, using a range of M68 extenders and the CZJ quick change system. It'a a closed tube design requiring no maintenance in the form of collimation, mirror cleaning, re-coating etc. A very well constructed telescope indeed...

I know how a Zeiss Jena pre World War 2 "E" 25 cm. objective got to the USA. It was in a leather case that was part of the personal property of Harry L. Freeman (1888-1953). It was mid 1945 and he was returning from Europe on a troop ship. His was a Department of the Army civilian tech advisor at a level of Maj. He was a long time member of the Los Angeles Astronomical Society In 1947 he was President of the LAAS. He had offered the lens to the LAAS if they would provide a mounting and observatory. They were unable to do so and the offer was withdrawn.

 

Mr. Freeman started a telescope company in 1948. I worked part time for him grinding and polishing mirrors. He did the final optical work. We talked about the lens and how he obtained it in war ravaged Germany. He traded a small amount of gasoline for it. We got it out of it's leather case one day and projected a solar image on a white card.

 

At the time the 24 cm. Zeiss was being mounted on the 30cm. Zeiss at the Griffith Observatory I talk with Tom Cave about that lens and the Freeman lens. He told me the 24 cm. was a much better lens than the 25cm. I think the lens was sold to some one in Texas.

 

I must be honest. While there was an exchange of gasoline for lens, it was war booty. I think I am the last person alive who knows this story.

Okay, another Zeiss beauty:

3e-koepel-kijkers-30-4-2015-Rob-Losscher

It has a bizarre history: This telescope mount is definitely ordered from Zeiss by the Leiden (The Netherlands) observatory in 1932. It arrived in 1938 with two dedicated cameras and a very heavy pillar from Zeiss in 1938. After WW2 the cameras were gone and a 60mm (or 80mm) refractor was mounted on it but rarily used.

In 2008 the Leiden observatory started to renovate their observatory. This mount had no antique value (unlike the other telescopes including a 10.2" Alvan Clarke refractor) so it was brought to a nearby museum. There they decided around 2013 to discard it. At that time one of my astronomy club members came in and he got it nearly for free. The pillar mount had to stay in Leiden though. Because of this, we designed a new pillar which as custom cast for our project.

He obtained it and he (and a few friends, me included) upgraded it so that it has a bigger RA worm gear, the former RA gear is now used on the declination axis and a lot of electronics, including a SiTech, were installed. It is still a Zeiss mount, but boy, it has radically been changed.

At the moment it is used as a mount for the solar telescopes, a 130mm f/6 apochromat, a 150mm Ha Lunt, a 60mm CaK Lunt and a 14" ODK telescope. Future plans: designing and making a 400mm solar telescope for this one, which will also integrate the other solar telescopes.

I still have almost no time for CN for the foreseeable future, but please enjoy some photos of a restored Zeiss 80mm A (f/17) scope.  The restoration was done by my friend Ray Taylor who is a CN member.  He is an incredible craftsman but this was a one of a kind project for him.  The tube was powder coated instead of painted and the focuser needed to be polished due to corrosion, so for those who need complete originality look elsewhere.  Like all the old scopes, it is solid (probably 13-14kg for OTA only) and the mount is heavy and rock solid.  Nothing today is made like this.  The optic is excellent although it needs a small adjustment to square it to the restored tube.

The other thing about Zeiss is that a lot of so called modern accessories were invented a long time ago.  Here is an astronomical binoviewer with eyepieces.  It makes the Baader binoviewer feel wimpy in comparison.  Lack of coatings makes the images dimmer than in modern equipment.  This one was out of collimation but was collimated by Cory Suddarth.

Derek, — beautiful restoration of the CZJ 3” A refractor! I love the focuser with graded scale, — Zeiss provided equivalent focuser scales also on the later APQ helical and the Meniscas scopes; Very useful for quickly zeroing in on the focus point when you’re often switching between visual and photographic (or other) backends.

 

     The mount above seems a bit lacking as a grab-go setup, as it does not seem easy to level, — and of course a motorized EQ mount (like the Zeiss Ib) would be preferable for modern applications.

 

     — Allan

I have 2 T mounts. The older T-1 is in much better condition that the T-2 which looks like it went through the Battle of Stalingrad. I also have a very old b-1 mount that needs some major repair due to shipping damage when it was sent to me from Europe.

 

What I am still looking for is a TM mount in very good condition before my time runs out. I have a 2VS tripod that came with the T-2 mount but looks like it was never used and has the metal tray
