A more detailed technical report on the Challis Observatory facility, telescope, instruments, and operations is available.
The observatory building was constructed on a 40’ x 80’ parcel of BLM land, leased to BSU, and surrounded by chain-link fence. Electricity, telephone and DSL network connections are routed up the Custer Motorway two miles from Garden Creek Road.
The observatory building is a 20’ x 12’ structure with separate telescope (12’ x 12’) and computer control (7.5’ x 12’) rooms. The heavy-duty construction roof was designed for much higher than anticipated snow loads. The roof rolls on I-beams, resting on six sets of casters on each I-beam – inside and outside – and captured closely by the I-beam to prevent lift-off in case the roof is open in extreme winds.
