And what to do with a 3m mirror when the Stockert already has two impressive and very successful parabolic mirrors?<\/p>\n<p>So, what could be more obvious than applying it for educational purposes &#8211; a stroke of luck for the Stockert learning center!<\/p>\n<p>What measures, what developments had to take place? We needed a stable mirror stand with a counterweight, a rotor control, a feed horn, an LNA, an astronomical control, a backend, an educational concept, and of course &#8211; people to make it happen.<\/p>\n<p>Thanks to a generous donation from the Rotarians Euskirchen Burgfey as part of their &#8220;Youth and Technology&#8221; project and the valuable support of Mr. Krosch, co-owner of the metal construction company Hecker&#038;Krosch, a suitable stand with counterweight was developed and built.<\/p>\n<p>A feed horn was developed and calibrated by ourselves, the limitations of the rotor were supplemented by additions to the mechanics and electronics, and the specially developed rotor control was tested.<\/p>\n<p>In July 2017, everything was ready, and a first attempt could be made. When a new telescope is first put into operation, it is called &#8220;first light&#8221;.<\/p>\n<p>This milestone was reached on July 28th.<\/p>\n<p>Subsequently, further setup, calibration, and further test measurements were carried out. Now, the new instrument is available and should be used by schools.<\/p>\n<p><strong>File attachment <\/strong>(only in german)<strong>:<\/strong><br \/>\n<a title=\"Feedhorn-Erstellung\" href=\"https:\/\/astropeiler.de\/wp-content\/uploads\/2017\/12\/BauanleitungFeedhorn.pdf\" class=\"mtli_attachment mtli_pdf\" data-mtli=\"mtli_filesize1133MB\" target=\"_blank\" rel=\"noopener\">Bauanleitung 21-cm Feedhorn mit einfachen Mitteln von Gerhard Stramm (pdf 12 MB)<\/a><\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/section>\n","protected":false},"excerpt":{"rendered":"On July 28th, 2017, the fourth radio telescope of the Astropeiler began test operations with a &#8220;First Light&#8221;.
