The 4.60 meters diameter dome was erected in 2002. The dome houses a optical telescope, with a diameter of 36 cm, as well as a solar telescope with a diameter of 4 cm and a focal length of 40 cm.
In 1999, the Zweibrücken scientific association was founded, with plans to construct an observatory. The construction was an initiative of Professor Peter Pokrowsky. The observatory is located on a hill in the Zweibrücken campus of the University of Applied Sciences, Kaiserslautern. In September 2018, the telescope dome was painted to resemble the R2-D2 robot from Star Wars by a team led by Hubert Zitt.
