In the summer of 2009, a new telescope was installed on the roof dome of our institute. It is primarily intended for educational use and, of course, it can be used by the Astroclub. By now the telesope is used for two lab courses, astrophotography, and some scientific projects.
The current version of the telescope manual can be found here.
