Telescope mount polar alignment scopes are typically not very user friendly. Having to get one’s eye underneath requires contortionism! York Astronomical Society member Graham Moore has come up with a brilliant solution: Buy a right-angled viewer made for a now defunct film camera and fit it onto the polar scope eyepiece. I bought a beautiful unused Olympus OM System Varimagni Finder through eBay.
My Varimagni has a square input end, which was for Olympus OM camera viewfinders. So making an adapter for a thing which is square and one end and round at the other was a bit like the emergency air scrubber adaption on Apollo 13.
I found a bit of Dural tube in my bits of metal box, opened up one end on my lathe to fit the ‘square’ on the Varimagni, and added a thumb screw to grip the polars cope eyepiece. (Not shewn in this photo.)
A dust cap completes the job.
