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).

    € 34.00 Price excl. German VAT tax (19%): € 28.57
    • Baader Turbo Film 127x51cm (Optical Density: 0,1). Use to protect your telescope and optical equipment against dust and humidity – without reducing the optical quality
    • This is the essence of AstroSolar safety film. A highest precision, crystal clear material (not “Mylar”).
    • It is a monomer film which we found after thoroughly testing more than 200 different film samples on our Zeiss autocollimator. This film was used in german Science Institutes as optical membrane for nuclear and particle physics experiments. The basic substrate has been further refined and homogenized by a proprietary annealing process that was developed exclusively for us.
    • Due to these treatments Turbo Film attains perfect homogeneity and performs equal to a 1/10 wave plane parallel optical window. In fact it has the lowest wedge error of any existing optical window. TurboFilm will protect your valuable optical equipment, close telescope tubes against dust and humidity, greatly reduce air currents – all without reducing the optical quality of your telescope.
