Abstract
BL Telescopii was discovered by Luyten in 1935 while searching for stars of high proper motion. Until 1948 this star was classified as an R CrB type variable by Kukarkin and Parenago. However, Cousins at the royal Observatory in South Africa observed this star visually from 1939 to 1945 and decided that it was a long period eclipsing binary. On the basis of his observations minima were observed on the predicted dates and it is accepted today that this star is an eclipsing binary.
