-Located in the eastern dome of the Elsässer Lab, MPIA operates a 70 cm f/8 Cassegrain telescope ready to be used by students as well as staff for practice, scientific observations, testing of new hardware, or just: fun. It's alternative name - King - was derived from the german phrase "Königstuhl Instrument zum in den Nachthimmel Gucken" ("Königstuhl Instrument for Night-sky Watching").

 Typical seeing conditions are around 2 arcsec in the visible, but can be as good as 1arcsec. Being located quite outside the city the brightening of the sky due to street illumination is acceptable, and using one of the interference filters gives a pitch-black sky indeed, allowing the acquisition of stunning images of emission nebulae like e.g. the Crab Nebula M1 shown on this page.

 While most observations performed with this telescope have no immediate scientific purpose, the telescope still plays a role in teaching future astronomers the basics of observing with a large telescope and professional camera. Apart from pure fun observations it has been used for a range of projects that place it in the same league as comparable telescopes at "real" observatories:

 Apart from these "big" projects regular maintenance tasks are unavoidable to keep it operating. These include major tasks like re-coating of the mirrors (next scheduled for Spring 2013) or minor tasks like improvement of the CCD's vacuum. Anyone willing to help with these duties is welcome.
 
-Access to the telescope is currently granted only to those who are acquainted with the odds and ends of correct handling of liquid nitrogen. The necessary training is given by Werner Laun, preferably not for single persons but groups to keep the time effort small. These trainings will be organised as needed.
