DIY telescope from Erich Kowald is ready for installation
The 50cm Cassegrain for Posiberg-Observatory in Styria is virtually a twin of our own telescope here in Harpoint or the 50cm Cassegrain of Kepler-observatory in Linz. The ancient telescope control by Manfred Stoll is used also in all 3 telescopes. An adoption of our Sortware supplements from Harpoint is planned. Both, the fork mount (ÖPFM) and the telescope tube, corresponds to the construction of Rudolf Pressberger. The design drawings of Pressberger had to be only slightly adapted to the different data of the optics. They were digitized by Erich Kowald complete with Autocad. Here we show pictures of the last test setup in the workshop before the telescope moves to the Observatory-dome.

DIY and ATM
Now available for our friends in the USA without translation software. Deserves special mention our series of articles from the construction of the great telescope according to plans by Rudolf Pressberger. This brilliant designer is still largely unknown in the English-speaking regions. The first two articles of the series are now available in pdf format.
