The "Musser" Copernican Planetarium.

Here's a picture of the latest find for my collection of orreries!  These machines have a really neat history, they were made as a commemorative for the 1962 Worlds Fair's "Century 21" space science exhibit in Seattle Washington (See the October 1962 issue of  "Sky and Telescope").  It was designed by Clair O. Musser.  The units were made by a company called Scientific Space Industries of Sherman Oaks California, a subsidiary company of the Hughes Aircraft Company.   This machine pictured below is marked with a serial number of 382.  These machines were never marketed, They were only available for purchase at the Fair in 1962.  I don't know how expensive they were. The neatest feature the machine has is a built in black light and florescent planets.  When you are viewing the orrery in a darkened room with the motor and internal black light running, the effect is stunning.  The planets appear to be orbiting the sun on a velvet background of stars!
It is truly awesome!
