HOORAY! The 65mm Russell has finally found its true home!
It really needed a scope like yours, Matt, with its slow focal ratio. It was wasted with my scopes. Its AFOV may be a little small, but the image it throws up really is beautiful. And it weighs nothing!
I have no regrets in having initially bought this 65mm eyepiece. It is a special piece and needed to be experienced and enjoyed
I still have its 50mm Russell Optics brother. It too uses Pentax glass like your 65mm, Matt. These Pentax lenses are very hard to come by now, even for Russell Optics. Very special pieces these. The 50mm better suits the instruments I have.
By the way, the most beautiful image I've seen through my old orange tube C8 from a dark site was using that 65mm Plossl! Its clarity, and the brightness of the image, the amount of pin-point stars right across the entire FOV, is forever seared into my mind's eye. So much so that I still remember where I was, and the occasion too. I really am very happy to see it finally find its true home.
Oh, and how is that eye relief with that 65mm!!!!
Freaking astonishing!
Alex.
