Baader Planetarium: Over 50 Years of Innovation in Astronomy

From accessories to turnkey observatories

The company Baader Planetarium is a middle sized enterprise having 50 years experience in producing and installing astronomical equipment.

More than 600 observatory domes of sizes from 2 m up to 8.5 m have been mounted, together with a large number of projection domes for planetarium installations up to 10 m in diameter. Observatory domes serve for a multitude of applications for scientific use around the world specialized to work under the hardest of environments, with installations in Antarctica (Dome C - 84°C) to high Arctic regions such as Svalbard (NyAalesund -45°C), Ellesmere Island (Eureca -60°C), in desert conditions with hermetic seals against dust and a number of high Alpine locations. Also the company specializes in high end robotic telescopes with apertures up to one meter as European sole distributor of Planewave Instruments USA, telescope mounts of varuious configurations, Echelle spectrographs featuring a resolution up to 20 000 lambda/delta lambda under Licence of MaxPlanck Institution(MPI).

    We explicitly warn against observing the sun with a DeepSky 3.5 nm (equivalent to 35 Ångstroem) H-alpha narrowband filter, specialized solar chromosphere and prominence filters from SolarSpectrum start at 0.8 Ångstroem. Photographic experiments with a camera are theoretically possible, but by no means observe the sun with naked eyes – you endanger your eyesight!
