The telescope is housed within a large, triangular wooden frame made of heavy beams and ladders. The telescope tube, labeled 'A', is a long, dark cylinder that slopes downwards from the top of the frame. At the top of the frame, a horizontal beam labeled 'H' supports a complex system of pulleys and ropes, with a group of pulleys labeled 'G'. The telescope tube is supported by a series of ropes and pulleys, with a label 'C' near the top of the tube. A platform with a railing, labeled 'B', is situated at the top of the telescope's support structure. At the base of the frame, there are two small buildings: a dark one on the left labeled 'D' and a lighter one on the right labeled 'E'. A staircase, labeled 'F', leads up to the platform 'B'. The entire structure is mounted on a large, circular base, which is shown resting on a textured ground surface.
