Arrived !! Just took some photos, my original one compare to SkyMeca's one, very nice job. I just tested them all one by one with my AS80/840, and it works just perfectly, like my original one :-)

Sorry for the multiplication of posts, but I didn't want to degrade too much the photos to put them. I have one left of each, just in case, one alu and one hybrid. PM me if some are needed, SkyMeca has some left too, but I have not "bought" them, but it is available, 5 pcs (either alu of hybrid since he made both male rings in duplicate).

Now I wonder... what if I could ask Skymeca to machine an M44 eyepiece holder for modern eyepieces, like 1.25” and 2”... with a brass compression ring inside. Ian mentioned it already, why not, I can ask.

When i bought my Telementor, the previous owner added a M44 to 1.25" adapter with compression ring, machined in anodized aluminum. It works, but maybe not the best solution when rotating the prism diagonal, but it may work for some users.

 

I will post pictures later to see if that is the same adapter we are talking about

Hello All,

 

Having just recently taken possession of Telemator C63/840, one of the very last produced I believe, I am more than content to live with tradition in continuing to use the 0.965" size of eyepiece, especially being in possession of a number of top class ortho. eyepieces of that barrel size. I also apply the same thinking with anything  else which affects the operation of the scope.

 

 In order to apply some degree of logic to the operation of an old scope in terms of accessories and observing needs, I've compiled a small matrix chart with  accessories listed horizontally and types of observing listed vertically. My observing needs are primarily astro.and, to keep friends and family happy, terrestrial.

 

The only problem is , I can't get hold of an original Zeiss porro erecting prism that was made for the scope. (any help here would be greatly appreciated). So what to do?  I believe 45 deg. viewing is more comfortable than 90 deg. for terr. observing - first issue solved. Second issue - porro or Amici? It appears the old style porro doesn't have the issues associated with the fine line potentially visible within the Amici design!  I've actually managed to acquire, second-hand, 2 straight viewing porros (0.965") but their quality is  somewhat visually and visibly below Zeiss in standard. In otherwords, getting a  0.965" top quality straight porro seems to me mission impossible.  I have just acquired today , from the USA, a second-hand mint Meade 1.25" straight porro, a  nice piece of kit, but again not quite up the standard I was looking for, it will do for time being. In the absence of any other advice, I've placed an order with OPT (USA) for a Williams Optics 45 deg. amici prism (1.25"), this for the time being will be the viewing  option for Terr. viewing.

 

So the situation is, I need to accommodate 1.25" nose- pieces ( as mentioned above) into the Telemator. I'am going about this with a Baader M44/T" camera adapter then attached to a Baader 1.25" Clicklock eyepiece adapter and thus have access to 1.25 facilities.

The William Optics 45 deg. amici fits into the Clicklock. This particular amici has a built in compression ring and thus should inflict no damage to 1.25" eyepieces.  However, I intend to use my 0.965" Zeiss eyepieces, to this end I have acquired  a reducing adapter (1.25" to 0.965") from Agena Astro, still awaiting delivery. The foregoing set-up should allow me to utilize 1.25" kit, as well as providing terr. viewing when required.

 

Without further testing, it's difficult to predict whether the terr. set-up will be up to astro. viewing, time will tell.

 

The matrix chart mentioned above makes sure I don't get lost in my endeavours, I page of A4.

 

In answer to Sylvain's observation earlier, yes, I'am definitely open to improve the mechanics of  my little system.

 

Regards to all,

Ian Lamont.

This is the adaptor i got M44 to 1.25":

nice, but not the best option for rotating the EP / prism diagonal

I was more thinking of this (your adapter) in conjunction with the quick coupling in M44, AND of course with the M44 diagonal: so, the M44–>1.25” on the eyepiece side of the diagonal:

Mmm,

 

Try the following, given in sequence from the scope:

 

Scope ----- M44-QCA (Zeiss or SkyMeca) ----- M44-Diagonal as illustrated above ----- A 'Conical' reducing adapter - M44 to a 1.25" nose ( yet to be made) ---- 1.25" eyepiece.

 

By conical adapter, I mean the one that is currently available  (metal and unfortunately plastic) which serves as the connection between the M44 female scope thread and the range of 0.965" eyepieces.

 

The missing link shouldn't take SkyMeca too long to rehash from the existing 0.965" current model, nor cost very much to make.

 

Cheers,

 

Ian L.

Mmm,

Just a further thought.

 

I'am very happy with the existing push-fit system between my 0.965" eyepieces and the conical adapter, both of course came supplied from Zeiss Jena.

Is it asking too much to expect SkyMeca to replicate the above (in terms of precision fit) at the level of 1.25" eyepieces?

 If it is too much, then I suppose the alternative is a thumb-screw fitted to the nose of the conical eyepiece adapter. A compression ring, in my book should be taken as standard.

 

Not forgetting Baader kit : one could utilize their 1.25" ClickClamp adapter for gripping eyepieces, not quite as elegant as above.

 

Cheers,

 

Ian L.

Hello Ian,

 

The "pinching" conical adapter of the Telementor works fine because it was meant to accept only Zeiss eyepieces, with quite the same machining standards and the same tolerances in barrel diameter. Today's eyepieces, from one brand to another, suffer a lot of variations in machining tolerances. Some Televue eyepieces can be quite lose in my diagonal, when other Vixen ones wouldn't even fit if I don't open the thumb screws even more. So, I am not sure we can achieve a universal pinching eyepiece holder nowadays, simply because of those huge tolerances from one barrel to another. Unless it is made of plastics with a wider movement possible. We have a seller in France who is selling a 3D printed system for M44 threads, see here :

Hello Sylvain,

 

You aptly define the sad reality of the world we now live in, mass market commercialism based on rapid and repeated turnover at costs which prohibit  long-lasting quality and precision engineering!

 

I agree with your observations.

 

Thumb-screw and compression ring remains the practical solution for an M44/1.25" conical adapter. The general shape would be as per the plastic version produced for 'Astronomy.fr'.

 

But certainly not plastic for me.

 

Cheers,

 

Ian L.

Hi,

 

I am just looking at the Baader site to get the additional ring that i need to attach the Quick change adapter to the T-2 prism diagonal, but i am not sure which ring is needed. (part #13 or part # 7)

 

From Sylvain pictures it seems M44 thread to the tube is already integrated, but just to be sure (and forget my inexperience):  the QCA is directly attached to the rear port of the Telementor, then the Skymeca ring comes next and another ring with a male T-2 thread (not supplied) is needed to attach the diagonal.

 

https://www.baader-p...auteil-07).html

 

is that correct?

 

Thanks and apologies for the question,

 

Carlos

A few years before I acquired my Zeiss diagonal, I put together this sketch of the sequence of Baader parts available at the time to provide for diagonal set up. Hope this helps ?

Many thanks Mike,

 

It seems that the Skymeca QCA already includes the M44 male thread (#13) but does not include the T2 #7 adaptor which is the one that connects to my T2 prism diagonal. 

 

I will wait until i receive it to identify the missing parts, but probably need a #7...

 The QCA from Skymeca goes from M44 to M44 indeed, for Zeiss diagonal and accessories. If you want to use the Baader diagonal (prism) in T2, you need this : between the QCA Skymeca and your diagonal.

part #13 then :-)

Hi All,

 

My Skymeca M44 Quick Change Adapter has arrived today.  I am very pleased with the quality of the machining and robustness (alu version). I tested it in the rear port without any issue. The retaining screw works perfectly and the system is very safe. Still pending to receive the adapter #13 from Baader, but it seems that will make the rotation much easier!!

 

Many thanks Sylvain !!

 

Greetings from Denmark

Carlos

Excellent, they should all arrive soon to their owners now :-)

there is one left at home (aluminum) and 5 left at Skymeca hybrid or aluminum.

First and foremost, I would like to thank Sylvain for all his efforts to provide a source for those of us who have searched unsuccessfully over time to finally acquire one of these highly desirable and sought after adapters. Thank You Sir !  

 

The Hybrid adapter arrived this afternoon, and I'm very pleased with the workmanship, fit & finish, and the visual appeal; it is definitely worthy of taking its place as a Zeiss accessory.  ubetcha.gif

 

Here are some photos....... 

 

Edit: I'm delighted the locking knob indexed precisely at 90* to the right of the peep sight, the perfect location for me.
