18" Astrola Observatory Reflector

John  Monforte at work on the scope

18" Observatory reflector. The telescope I rebuilt was the one pictured on your site as the 18" Observatory reflector. It was built for Henry Gibson of Palm Beach FL. I had the mirror ground for a shorter focal length and put a hole in the middle of it and the mount. This way it can be used as a wide field Newtonian or a Cassegrain. I also added encoders for a computer running the Sky software. It is still at the U of Miami, but the Observatory was moved to another building and I don't know what condition it is in.

I spoke to Cave at one point during the work, to find out what I could about it. He was not very happy to talk to me, but I did find out it was the one in the ad and the only one like it.
