Abstract: A tracking mount (102) for an astronomical equipment includes castellations (226) in a semicircular arrangement at a first end of a base member (114) having a through hole (214) formed at a radial center of the castellations. Additionally, the tracking mount includes a tracking arm (112) having a shaft extending perpendicular to a long axis of the tracking arm and a set of teeth (508) formed at a position distal to the shaft. The shaft has a notch (210) formed at an end opposite the tracking arm. The shaft is dimensioned to be inserted into the through hole. A coil torsion spring (218) having a crossbar (220) formed at one end is mated with the notch on the shaft. A selector structure (224) formed at another end of the torsion spring is dimensioned to sit within a castellation of the plurality of castellations to adjust the torsion coefficient.

Abstract: A Crayford focuser includes a body member having an inner wall defining a central channel. A first bearing holding structure extends outward from the inner wall and is open to the central channel at one end. A second bearing holding structure extends outward from the inner wall and is open to the central channel at one end. First and second bearing rails are removably held by the first bearing holding structure and the second bearing holding structure, respectively.
