The designed setup if the observatory includes two mounts with double scopes. The GM1000 is positioned in such a way that shorter tubes are required – to stay clear from the walls. Today both the 180mm Mak and the 76mm APO were mounted together. The NUC serving both scopes was mounted on the dual saddle plate.
For the GM2000, which today only carries the C14, in a next phase also the Esprit 120 should be mounted.
