Since september 2003 our institute possesses a 0.8m reflector built by AstroOptik Keller, placed in a 5m dome by Baader. It has a focal length of 6.40m (f/8, with focal reducer f/4) and two Nasmyth foci. Details can be found on the websites of the producers.




We use ST-V, ST-7, ST-7e (incl. filter wheel CFW8, Johnson BVRI) and STL-1001E (incl. LRGB, Johnson UBVRI, BG40, Hα, Hβ, O iii, S ii and He4686 filters) by SBIG, and a HX916 by Starlight XPress. Details can be found on the websites of the producers. Furthermore, our institute possesses a spectrograph (10C Optomechanics), which is used especially for educating purposes. For the wavelength calibration we use Hg and Ne.
