I'll be looking over some other threads about restoration of the RV-6 and working on it over the next few weeks. It is in surprisingly good shape. I haven't removed the primary yet but it looks great gazing down the tube.
I couldn't wait to complete the restoration for first light so I mounted he rings on a Vixen dovetail and mounted it on my iOptron zEQ25 to give it a try tonight. I was completely blown away! Views of the Moon are the best I've seen with ANY scope (250X). Took a quick look at Venus which was fairly low in the Southwest and M31 which was nice and high. The best I've seen either of those without a camera.
I mainly bought the RV-6 to clean it up and sell it... after one quick session, I think I'll keep it. I may leave it mounted on a modern mount, but the OTA is a keeper. The only issue I have to address now is that the collimation is so good that I HATE the thought of taking the mirrors and focuser off to repaint it. I think I may just keep it like it is, warts and all.
