On this site we collect images taken by students at the astrophysics department of the university of Potsdam as part of the astrophysical lab course or in their spare time.

• This site was initiated and written by Nadine Giese and Fabian Krause.
• Most of the images are taken with our 14" Schmidt-Cassegrain telescope, which we named OST (our small telescope or overwhelmingly small telescope). The solar images are taken with a smaller 11" Schmidt-Cassegrain telescope.
• We use a SBIG STF8300M CCD-camera, a SBIG ST-8 CCD-camera, a Philips ToUcam-webcam, as well as various DSLRs (Canon EOS 450D, Canon EOS 700D, ...).
• We collect and organise various information about our telescope in a wiki.
