Hartmut Frommert's Schiefspiegler
My instrument is an 11-cm f/24.7 Kutter Schiefspiegler in anastigmatic
construction, i.e. consisted of the two mirrors only and not needing a
correction lens. This telescope, with its optics from the Belgian
manufacturer Lichtenknecker, was constructed from a kit offered by the
Kosmos company from Stuttgart, Germany, and had its first light (planet
Jupiter) on September 1, 1973.
