During the last thirty-three years a considerable amount of work on the observation of Miner Planets has been carried out at the Union Observatory in Johannesburg. This was the result of the gift to the Observatory in 1909 of the Franklin-Adams Star Camera with its powerful photographic triplet lens of 10"" diameter and focal length, i.e. an aperture of f/4.5.
