Interesting. An in-baffle tube field flattener. I'd probably have made
it outboard and a f-stop reducer, but this still looks good. Figure
maybe $5000 for the OTA and $10,000 for a mounted scope. The mount
will likely include modern electronics, perhaps Goto. Scroll near the
bottom of the page.

This is actually a diffraction-limited telephoto lens of long focal length.

Can you replace the eyepiece with an T2 mount adapter? Thinking DOF here...
