Hi
Anyone have any clue or suggestion on how to mount a Zeiss scope with a standard Zeiss bar onto a non zeiss Mount via an adapter so tube rings are not an option.

We would need more details on the mount you want the Telementor on for your adaption.

I think the OP means a mount accepting a standard Vixen dovetail rail. Since the Telementor has a mounting rail of slightly different cross-section than the Vixen rail, and since it is flush-mounted to the tube, it won’t fit on typical Vixen and Vixen-clone mounts (the ones that use the thumb-screw that pushes the bar directly into the jaw).

 

I wonder if this type of clamping jaw will work? (I’ll check it out later with my Telementor and let you know.)

I just tried it and it doesn’t work. While it works great with the Vixen bar, it falls short of about 1/16 of an inch in securely locking in the slightly narrower Zeiss mounting bar.

Thanks I wonder if the Baader/AP clamp would work. Seems like it should.

Can you replace those screws with longer ones so that they could reach the smaller size rail. Or is that vixen clamp solid and not possible to dismantle?

If it's a Vixen mount/saddle, Astrojensen wrote a thread some years ago, ''Vixen and Zeiss dovetails'' he changed the bolt on the saddle for a longer version and said it worked fine,

AP adopted the Zeiss dovetail standard, so AP clamps fit Zeiss dovetails.

Yes. It's not perfect, but it works. There's no safety, though, so if the bolt loosens, the scope could drop.

They could be changed out without a great deal of trouble.

How about adding a piece of 1/8“ th by 1/2” wide strip of aluminum bar stock to the rail face opposite the clamp.....? Or add it to the fixed (non traveling) side of the clamp.

So this would work if purchased and bolted on to a universal dovetail?

From what the description says it might work. Like the two bolt fasteners. Solid looking.

So those longer M5s are long enough to thread back into the OTA I’m guessing, which secured it all down nice and tight.

Yes, the longer M5s thread into the OTA which secures both dovetails.

I would suggest using stainless steel M5 screws, as rust will develop on ordinary steel ones. You can soak the stainless screws in a solution of black oxide & water to blacken the threads which may extend into the tube.

That would do it. I would also shim the rail floor of the clamping jaw. As it is, the Zeiss rail doesn’t bottom out in it.

My solution thanks guys for the suggestions. With my original question and your suggestions I’ve slapped this together with minimal effort.
