This 5.5M wide observatory dome is made from 6mm glass polyester laminate (GFK), which guarantees complete protection against all environmental influences, simultaneously providing a high level of stability and guaranteed longevity. A proprietary special reinforcement rib system on the inside of shell  construction, provides additional rigidness. The water tightness of the dome is warranted by a special design of labyrinth joints and surfaces, that prevent ingress of water or snow in the dome.

A large, "dome-around" air gap in the base ring prevents excessive daytime heating of the interior and easy temperature equalization during nighttime observing, when the dome is open.

The large observing window, with a width of 1m, allows unhindered observing for telescopes with diameters of up to 50 inch alt/AZ and equatorial up to 30". The observing window has been designed in such a way, that an unobstructed view of the zenith is possible.

OPTIONS

In the "full"-version the dome comes complete with all all necessary motor hardware for dome rotation and  shutter window. All control electronics is house in patented watertight cabinets.

The dome electronics are 100% ASCOM compliant and feature standard dome/telescope sync, power management, sensor suite, proprietary software. At wide range of weather stations can be interfaced with the dome's control system to trigger dome safe-mode events. The DOME PARTS TCS/OCS  system supports remote and robotic operation, worldwide, either cable or satelite based.

ATTENTION:

Due to its weight, its dimensions, its special requirements and in particular for saftey reasons we advise that your 5.5M dome is constructed by a qualified construction team.

Both the 4M and 5.5 M domes are installed on a concrete ring foundation, or our proprietary steel support structure ring system (SSRS). 

Upon ordering the 5.5M observatory dome, DOME PARTS GmbH will give you all technically relevant information and a ring design, so your local building contrator can pour your foundation.
