Penteli Newall Telescope in action

The Newall refractor telescope, located in Penteli, is the most impressive instrument of the National Observatory of Athens. Its tube is cigar-shaped and it is approximately 9 metres long. The observations are facilitated by a mobile floor, which can move vertically for approximately 5 metres and by a rotating hemispheric dome. The whole telescope weighs 9 tons, but the instrument is so evenly balanced that, despite its weight, it can easily be moved by the observer, as seen in this video.
