25cm Gajdusek-Kozelsky Cassegrain

The 25cm Gajdusek-Kozelsky Cassegrain was made in the 1960's for the Zdanice Observatory in the Czech Republic.  The mirrors were made by Vilém Gajdusek (1895-1977) and the mechanics by Frantisek Kozelsky (1913-2003).

In the Zdanice Observatory I found two of this Cassegrain reflectors.  One is already completly restaured. 

Originally the telescope was "portable" with a weight of 25kg.  It was mounted on a portable pier with an alt-az mount.

The main mirror has a diameter of 25cm with a focal length of 3700mm.  This is thus a f:15 telescope.  Excellent for planetary observations.
