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).

    • Blaze Reflection Gratings 1200 L/mm
    • cemented onto Tilting grating holder
    • For high resolution observations where the 900 and 1200 gratings are used, Dados (by construction) is expected to provide the best optical performances in a short spectral range (30 nm). 
    • It needs to be pointed out to any prospective user up front that the 1200L grating has been addded later on some customers insisting demand, for projects that concentrate mainly on the H-alpha region – to attain max resolution there. The 1200L grating however cannot show the full spectrum and the tilting range is limited to H-alpha mainly. In case this restriction is not acceptable, this grating ought not to be part of an order.
