I recently bought a Zeiss 44mm prism for my Telementor I and would like to find the Zeiss quick change unit (pictured) that would allow not only changing out to my amici turret but mainly to rotate the prism to a proper viewing position like a CAA. Is this an item that ever shows up for sale and/or is there someone in this forum who may have one to sell? I know I can adapt a Baader quick change but would prefer to try to find the Zeiss first.

 

Thanks,

Gordon

These are getting very hard to find, unfortunately. Someone should bug Baader into start a production up again.

They come up on eBay, occasionally. Prices are insane, though.

I just bought one of these:  Blue Fireball Gender Changer: T / T2 Male-Male Thread Adapter # G-TM  -->  http://agenaastro.co...anger-g-tm.html

 

Is that what you're looking for?

That by itself wont work with a Telementor. You need this:


- Zeiss Camera-adapter M44e/T-2e (outer) (# T2-13)
These adapters allow you to convert Zeiss telescopes and M44 accessories to the Baader T-2 standard. Zeiss telescope and equipment owners will really appreciate the new flexibility they gain from converting over to the Baader Astro T-2 System. We've outfitted many Telementor users with our quick change system and prism diagonals, using a T2-13 adapter. Owners of Zeiss M44 eyepieces can now convert them to 2" barrels, by simply adding a T2-09 and a T2-16 2" Nosepiece. Or, convert the superb Zeiss M44 prism diagonal or amici turret for use with 2" focusers and 1.25" eyepiece holders. These adapters also let you convert the M44 input/output threads of the unique Zeiss Position Circle (#T2-12) to T-2 thread.

You can get it from Alpine Astro. The reason being that the basic threading on the Telementor is not T2, it's M44.

Alpine Astro also has the Zeiss-Baader quick changer system:

Heavy duty T-2 Quick Changer System #T2-6A,7 is a combination of parts #6A and 7 This is a much improved product in Baader's Astro T-2-System portfolio of telescope essentials. This changer-combo works similar to the standard T-2 Changing System #T2-6,7, but it is suitable for extremely heavy duty accessories. The difference between both Systems is part-no.6 versus part-no.6A. The (T2-6A) T-Quick Changer (with Zeiss pressure block) literally equals the Zeiss-original - only it incorporates a contemporary T-2 female thread (M42x0.75) instead of the Zeiss thread of M44. We are glad that this T-2 clamping/rotating system now is fit for the next 25 years. It will fasten almost any load with utmost security.

As far as I know, Alpine Astro is the only supplier in the USA for the complete Zeiss-Baader line.

I keep forgetting that, but then I am new to this CZJ universe.  (Yep, that's my excuse, and I'm gonna run with it.)

It will handle that easily. The dovetail rail (which you have no doubt already noticed is not Vixen Standard- it's the same as ADM Dove08) is plenty long to easily compensate on changing loads at the rear of the OTA.

Thank you all for the input. Looks like I'll be going with the Baader QC and 44-T2 adaptors. I use the Heavy Duty Baader QC on another scope and it does work well. Looks like $264 for two rings, the HD QC and 2 44-T-2 adaptors (in and out). 

 

Do the Zeiss show up for more than that?

An original Zeiss M44 Ring dovetail, if you can find one, usually cost about $150 - $300, because of their rarity. It depends heavily on the seller. To some, it's junk, because it doesn't fit anything else, and they're basically willing to give it to you for a symbolic sum (that has yet to happen to me...), to those who know what it is, it's a rare item, almost worth its weight in gold.

 

Be patient and keep looking, if you really want it. Myself, I'm just sticking to the Baader adapter, refusing to get financially skinned by an opportunistic seller, that has done ten minutes research on eBay...

As Thomas said, these Zeiss accessories are super high priced if purchased separately.  The best thing to do is to buy a scope bundled with accessories and then sell the extra stripped version to someone else if you can afford it.  With the M44 changer at 200-300 Euros and a finder listed at 450 Euros, you can spend double the price of the Telementor OTA just on those accessories.

 

Here the German terms for the two pieces, assuming that the ads have the correct spelling:

 

Wechselvorrichtung
http://www.ebay.de/i...=p2047675.l2557

 

Wechselring
http://www.ebay.de/i...qcAAOSwgyxWVsYo

 

Here is a photo of different rings.  One of the reasons that the M44 changer is valued is that it is substantially larger than the Baader T2 changer.  One of my friends in Germany implied that the Baader version was for girlie-men (no disrespect toward women intended!)  The photo shows (from left to right) an M68 changer that is similar to one Baader makes (175 grams), the M44 changer (205 grams), and the Baader T2 "heavy duty" changer (65 grams).  The one below is a brass version that is even heavier; the clamp ring is part of the focuser drawtube: http://www.astromart...99/886912-4.jpg  In use, although the Baader is solid, the Zeiss feels like you can clamp it as hard as you want and nothing will budge.  Older scopes have a clamp mechanism that is even nicer.

I have found most of my Zeiss adapters on the German ebay. I search for the quick changer with "zeiss schneller Wechsel"

I think there is a half of a quick changer (left in your picture) on the site now.

Yikes, the prices have become even more insane. 200 euro for *each part* of a ring dovetail? And over 800 euro for a finderscope?? That's just insane.

Hmm, I got one bayonet end with Zeiss helical focuser. I paid 40Euro 4 years ago for the whole set. Seller was asking this price and it seemed a fair one.

Thanks for all your input! I was able to find a Zeiss set from a guy in Germany for $270 which is "only" $50 more than the heavy duty Baader with adaptor rings so I figure it was an OK deal and will look good with the Zeiss zenith prism.

Holy cow Derek! You don't mess around when it comes to bits and pieces. I see the adapter I have third from the left. I also have a black one with the same configuration. Yea, I definitely want to show you the Zeiss bino to have a closer look and get your thoughts. Not sure about this but Pons mentioned something about the coating on the older models being really good. I really love this older looking model. Vernon and I spent many years with it.

Derek, I checked company 7 and this is it.

The black adapter hooks straight onto the Baader 2" nosepiece for straight through observation and clamps onto the nose of the bino. Makes more sense now.

Did anybody tried to measure the original part and produce the drawings?

It would be useful for machining the replica, or for 3D printout.

3D printing won't work, it's not strong enough (at least if you're using plastic). 

 

Machining the male adapter on a lathe is extremely easy and straightforward, the female one (on the scope, with the clamp) is a little bit more tricky, but still easy if you got a mill with a rotating table. 

 

Sadly, I don't have an original M44 coupler, so I can't make some drawings or contact local machinists and get some quotes.

Figuring out how to make M44 metric threads on my old South Bend lathe would give me a migraine headache.   But 3d prints in nylon or polycarbonate are almost feasible.

Not that hard to machine. But setting it up takes time.

Hi All,

On my AS80, there was, including the scope, a quick changer from Zeiss M44 to M44 via a dovetail ring quick connector... love it, it makes a lot of sense with the diagonal from Zeiss.

BUT, I wanted to have the same one for my Telemator, to use my Zeiss diagonal on it too... and indeed, it's close to impossible to find one.

 

Having said that, there is a machinist in France, about 1h away from home, a small family business called SkyMeca. The owner is specialised in making all kinds of rings and adapter for astro gear purpose, he is very well known on our French astro forums. I did send him a request of feasibility for a duplicate of my Zeiss system, M44x1, dovetail ring. He thinks it's possible, so most likely I will lend him my Zeiss unit and see what he can machine, and hopefully at a good price.

 

Here is what it looks like, the original. Hopefully SkyMeca can make me another one, I will sure let you know here.

If he can make a good, working copy, he has some business opportunities. I'd be QUITE interested in getting one myself.

Sure, I will let you know, maybe I can ask him to get half a dozen made in order to lower the price.
