- The telescope was a refractor with a 27-inch lens. The lens was supplied by Jena in Europe and was of exceptional quality and had great resolution power. It was the biggest refractor in the Southern Hemisphere when it was installed in 1928. The telescope was temporarily installed on its base just outside Detroit
Observatory of the University of Michigan, Ann Arbor. It was taken to South Africa in November 1926. It was primarily used for the discovery and measurement of double stars.
- When the Observatory was closed down Michigan University gave the building and telescope away free of charge: the telescope fell into the hands of the Municipality and the building went to PACOFS. PACOFS took good care of the building and is still maintaining it. The telescope met a more unfortunate fate, though it is still salvageable. The telescope consisted out of a tube (consisting of two segments), a counter weight and a foot piece. These parts are currently housed in the Fire Station Museum in Bloemfontein. The optics of the telescope went back to Michigan University where it is currently in safekeeping.
- Part of the Bloemfontein branch of A.S.S.A. is an organisation called the “Friends of Boyden”. Their members has done stirling work in tracking the individual parts of the telescope and moving it to Ehrlichpark Fire Station Museum. For more information click here.
