Default Questar 5 specifications released:

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.
