Leica Televid 77 astro adaptor
 
Does anyone know of an adaptor that allows 1.25" astro eyepieces to be used in the Leica Televid 77 scope? I know Company Seven do one at >$400 which is too expensive.

On a related tack, the photo adaptor attaches to the prism housing by means of a screw thread. Does anyone know details of the screw thread i.e. diameter and pitch, or whatever technical spec. is used to describe it? I might try to make an adaptor and the screw thread is the hardest bit!

It does strike me as odd that there is as far as I can tell no reasonably priced astro adaptor for this scope.

No! I have the opposite, an adapter which allows the very nice Leica 20-60 zoom eyepiece to be used as a 1.25" eyepiece in an astro scope. (For sale, if anyone wants it ....).

When I was looking round, I could not find a cheap version of what you are looking for anywhere.

I contacted Leica in Germany and they were very helpful. They informed me that most 1.25" eyepieces cannot reach infinity focus with the Leica APO Televid 77. There is an exception - the Zeiss Abbe 4mm Orthoscopic - and a small adaptor is readily made. I have a Vixen Lanthanum 4mm eyepiece - bought used - and I reckon that the eyepiece could be machined to fit. I might have a go.

did you get anywhere with this?

am considering a leica 62 if i can find an adapter.

i have used astro eps on a busjnell spacemaster, but find only ones of a certain height will work; longer ones just dont come to focus.

thanks
