Most people want to use microscope eyepieces in telescopes, but I was wondering if there were any adapters that would do the opposite, and be able to use a telescope eyepiece in a microscope. Are microscope eyepieces the same size as the older eyepieces - as in 0.965" eyepieces, or are they slightly smaller? I have read they vary from 23.2mm (0.91338") to 30mm (1.1811"). Do they vary by age of the microscope, as in newer ones are 30mm, and older are 23.2mm? I have a friend with some amazing older Zeiss microscopes, and would like to compare the views with a Delos eyepiece (1.25"). Any help with adapters or how to accomplish this would be amazing! Thank you in advance! :grin:

You could fit .965" telescope eyepieces into 30 mm. microscope eyepiece holders (and the combination would work), but modern 1.25" telescope eyepieces won't fit. AFAIK, there are no adapters for the latter adaptation, and even if there were, the telescope eyepieces likely wouldn't be able to come to focus in the microscope(s).

Thank you for the response snorkler! That was what I was hoping to hear. I actually have found some 0.965" to 1.25" adapters to use newer eyepieces in older telescopes, so hopefully they will work as far as fitting them in the microscope. Unfortunately, I think you might be correct in coming to focus with the adapter + telescope eyepiece, since the focal plane will be raised higher than normal...
Worth a shot regardless, and I will inform the forum either way of the outcome in a couple of weeks.
Thanks again for the response! :grin:

Many years ago I made an adapter out of PVC enabling me to use a 4.8mm Nagler eyepiece in my microscope.

The link worked last night, but at that time I was logged in to the archives.

Thank you for those pictures star drop! Looks like an easy enough project for me, especially using PVC. I guess if I can do the plumbing for larger fish tanks, this should be something a lot simpler to accomplish :)

The adapter required some sanding to fit.
