Friday September 18th, 6:00 p.m.:
Prof. Dr. Matthias Steinmetz belongs to the scientific leading group of th
Potsdam) (AIP). His lecture
"The telescope - a cosmic time machine" :
A view through a telescope shows distant and past things as well. With
larger instruments we see more distant features and more past events.
The 5-meter-telescope at Mount Palomar was the leading instrument for
25 years. The next 25 years the 6-meter-telescope at Caucasus mountains
takes this place. Since the mid-90th we have larger and larger
instruments in a quick succession. Our largest telescopes have 6-10
meters aperture now. The preliminary climax is the Large Binocular
Telescope with two 8.4-meter-mirrors. It is locates at the Mount Graham
in Arizona. The AIP takes part in erecting an using this instrument.
The future will bring us even larger telescopes..."

The predictive value of Sky Quality Meter (SQM) measurements: At the HTT we have suitable conditions for
checking the SQM:
1) Many astronomers are at the place. We hope to have a sufficient number of SQM devices at
Very good night sky, as well astronomical and meteorological. We will
be able to investigate the influence of the milky was and the zodiacal
light on SQM measurements. Bernhard Engeser collects such values since
2006 and will be offer the results in a database. The most important
results will be published in astronomical periodicals. We ask all
astronomers to join this project. If you own a SQM please have it with
