I like how it has a rifle scope!

Well, that's the longest focal length catadioptric system I've ever heard of. I like how it has built in ND filters as its .5 meter mirror probably soaks up enough photons to start a fire.

220#'s ? Yikes!

Any mention of price? I haven't been able to find much mention of this lens other than its debut in the 60s.

Anyone notice the actual camera hanging off the back?

Reminds me of these guys they use to track space shuttle launches:

There is one of those parked downstairs in the hangar I work in. No optics attached, just the mount. I have no idea what they use it for.

For reals? Those things are serious money. It took me 5 minutes of GISing just to find that tiny pic.

Yeah, it was just parked next to the tool crib. I'd take a photo, but that sort of thing isn't allowed. There might be another one in the parking lot. They have a big fiberglass clamshell cover that goes over them, not those fabric covers like that picture shows.
