Eilenburg observatory
The “Juri Gagarin” observatory in Eilenburg is an observatory and planetarium in the Saxon city of Eilenburg . The device forms with the Astronomical Center Schkeuditz the observatory Nordsachsen based in Eilenburg, which in turn is part of the district-owned educational and cultural affairs and in sponsorship of the district Nordsachsen is.
history
As early as 1931 there was an amateur observatory in Eilenburg in Kastanienallee opposite today's Schützenhaus. In 1961 it became the school observatory for the Eilenburg district . In 1963 and 1964 the construction and subsequent relocation of the now public and school observatory to a new building on the hill Mansberg in the Berg district took place. The facility was now the second largest school observatory in the GDR.
A planetarium with 40 seats was built in the immediate vicinity and opened on October 21, 1965. In 1976, the Soviet cosmonaut Pawel Romanowitsch Popowitsch visited the observatory. Until 1983 Eilenburg was an official satellite observation station . The railway data were transmitted by telegram from Moscow , and the measurement results were then reported back to Moscow from Eilenburg. Some amateur astronomers also used the telescopes as part of the Moonwatch organization (USA).
Since the end of 1996 the observatory has had a new, powerful, computer-controlled reflector telescope with a 305 millimeter aperture as the main instrument. In addition, the observatory was involved in the creation of the first planetary hiking trail in Saxony, which leads over a length of 2.8 kilometers and on a scale of 1: 2.1 billion from the pioneer bridge in Eilenburg to Bobritzer Damm. From 1964 to 2004 the observatory had around 315,000 visitors.
Technical Equipment
observatory
The main instrument is a 12-inch Schmidt-Cassegrain reflector telescope from Meade Instruments Corporation . In the observation tower there is a 6-inch refractor with a focal length of 2.60 meters and a Zeiss lens , two solar telescopes are also available: a Zeiss refractor 80/1200 with a sun protection filter for observing sunspots in white light and a Vixen refractor 80 / 910 with protuberance attachment for observing the sun in H-alpha light .
planetarium
The planetarium has a dome diameter of 6 meters and has 40 seats. It is equipped with a ZEISS ZKP-1 projector.
Research work
The Eilenburg observatory is working on two international observation programs. On the one hand, this is the daily observation of the sun with a special telescope, during which sunspots are observed and logged. With the help of these observations, the sunspot relative number is then determined, which in turn is transmitted to the Solar Influences Data Analysis Center (SIDC) in Brussels . On the other hand, entries and exits as well as grazing star coverages on the moon's edge are measured and logged. This data is reported to the International Lunar Occultation Center (ILOC) in Tokyo .
Educational offers
From October to the end of March there are regular public observation evenings on the telescopes. In the planetarium there are year-round lectures for students of all grades as part of the lessons. In addition, there are family and special children's shows during the school holidays and on some Saturdays.
