(position and motion) and photometry (brightness and colour) of stars in our Milky Way have been published. Eventually, the "Observatory Hoher List" lost its former scientific standing because scientific observations became more and more difficult in the Eifel region. The brightness of the night sky had increased, the weather conditions and quality of instruments were inferior to those of the excellent observing sites in Chile or in the USA. Therefore, the observatory started to serve for the practical part of student education and provided a laboratory for the development of astronomical instrumentation that could be implemented in telescopes e.g. in Spain or Chile. Shut-down and further utilization In February 2012, the Argelander Institute for Astronomy ceased any scientific education and observing completely, and the University of Bonn shut down the observatory in July 2012. The scientific instrumentation, including all telescopes, were to be vended thereafter, which was actually done in case of the 50-cm Schmidt telescope. The Schröder refractor was transferred to Bonn for a permanent exhibition. In September 2013, the observatory was put under monument protection by the Landesdenkmalpflege Rheinland-Pfalz, in order to prevent its full dismantling. One month earlier, the former observatory's friends' association was renamed as Astronomische Vereinigung Vulkaneifel am Hoher List e.V. (AVV). Since then, this non-profit club maintains the observatory by carrying out regular guides, public talks and observing events for the public. On March 1, 2020 the real estate with its observatory was purchased by a former staff member. Since then, the AVV has access to all telescopes at Hoher List so that the range of activities for visitors could be greatly expanded. A recently applied new silvering of both, the 1-m and the Ritchey-Chrétien telescope furnished these instruments with optimum imaging performance. The following table lists the current instrumentation at Hoher List Observatory. Guides for visitors, which include a talk on astronomical themes are taking place on Saturdays between April 1 and October 31, starting at 3 p.m. From November 1 through March 31, starting at 8 p.m., observations with telescopes of Hoher List Observatory are offered to visitors as weather conditions allow. Public talks given by experienced amateur astronomers and by university lecturers of astronomy on various astronomical subjects are held every third Wednesday of the month, from February through November, starting at 7 p.m., with observations offered thereafter. AVV members and visitors convene every Tuesday at 7 p.m. In case of
