Yes but mine, apparently is an older 60AZ- S model. The eye piece holder has an inner diameter of 2.5 cm; just under one inch.
I bought and returned the Bushnell and Celestron adaptor hoping I could thread one of them on somehow inspite of them not fitting as they should down in the eye piece holder. I thought one might even thread onto the focusing tube but alas...
I think someone on this thread brought up an issue of focusing if adaptations are not correct so I may just look for a nice $10-$20 scope at garage sales this year.
One inch eyepieces are very uncommon nowadays. That used to be a more common diameter in the distant past... You may find adaptors from 0.965-inch (I think, that should be the correct size) to 1.25-inch easily, as therer are many orthoscopic eyepieces around, which have that small diameter and need and adaptor. Even Pentax sold these eyepieces until three or four years ago new. BUT the diameter is so small, that I wouldn't use it for photographic purposes, as the illumination (aka vignetting) might be quite noticeable. On the other hand, at 700mm fl, you get a moon image of app. 7mm across, which will sure fit into the illuminated center of the image.

Well, all hope is still not out! You can get 0.96" to 1.25" adapters:

TELESCOPE CAMERA ADAPTERS |TelescopeAdapters.com - Telescope Hybrid Adapters & Extensions

Based upon such you can then expand with 1.25" and T2 photographic couplers.

Better still - but I don't know the details of yor scope:

If you could connect a T2-ring directly to the draw tube you would be better suited for prime focus photography. On my vintage Vixen Polaris R-100L (also a .96" system) this works as follows: Inner 36.4 mm thread on draw-tube --> outer 36.4mm thread to outer T2 thread adapter --> T2-ring. That way you will get very little vignetting on film and none with an APS-C sensor in prime focus.

Anyway, here is a picture of the 0.96"-to-1.25" type adapters that are still available:

When I started in astronomy back in the 60's, these were known as Japanese eyepieces and were mainly provided by Japanese telescope manufacturers. 1.25" (RAS standard) eyepieces were quite hard to get in NZ at the time, and prohibitively expensive. Fortunately sanity in the market place has prevailed.There are now 2" eyepieces available, probably due to the advent of large aperture light buckets and optical designers like Nagler.

Yes, the Japanese stuck much longer to the smaller 0.965-inch eyepieces, including the big and famous brands from Pentax and Vixen right to Kasai. But I also have a whole set of German Zeiss Orthoscopics of that diameter. I made my own adapters on the lathe, which are fitted permanently to these, because I hate to fiddle with the avalaible nifty adapters in the dark...

Thank you.
The shot was taken something like 30 minutes before sunset about a week ago when the moon would rise a little sooner than it does today.

That's a nice one, because of the mood. No howling Werewolves around the corner?

With a little help from you, Ben, I might find some, I reckon! Alternatively, perhaps a witch on a broom, as my wife suggested. I also thought she could help me out, but she seemed less than enthusiastic for some reason...
