SAAO 0.5-m Telescope
The 0.5-m telescope was built by Boller & Chivens in 1967 for the Republic Observatory, then moved to the current observing site near Sutherland in 1972. Telescope specifics are listed in the table below; the optical diagram is given in Figure 1.
|Cassegrain Focus||f/18, 22.6 arcsec/mm|
|Guider-Finder||100 mm f/9.1|

A PC runs the Modular Photometer using the program LUCY (all-sky photometry) or MILLY (uninterrupted observations on one object with one filter with integration times in the range 2 ms-60 sec). A printer is available in the nearby 0.75m dome.
Special equipment should weigh less than 25 kg and be less than 1 m long. The layout of mounting holes for fixing instruments is shown in Figure 2.
