Cave Optical was one of the big players in the Telescope market during the 60's and 70's. They sold Astrola Telescopes. I use to get their large catalog through the mail and examine every telescope that they offered. They offered a lot. Some of the 12 to 18 inch scopes were quite impressive. They even advertised institutional scopes, up to 24" weighing in at 4000 lbs.
I lingered long on the cassegrain scopes. My favorite was the 10". I've scanned a 70's vintage catalog and will post it over the next few days. I've never read anything written by any owner of a Cave cassegrain and would be interested in hearing from anyone who owned one.
