A Dark transit of Titan seen from Australia with a Cooke telescope

On November 5^th / 6^th 1907 Mr A B Cobham and Mr G D Hirst using a 4.5 inch Thomas Cooke & Son telescope in Australia saw a dark spot on Saturn. This was afterwards ascertained to be Titan.

They also both commented that they caught glimpse of the edge of the ring at flashes, the impression indicating the extreme fineness and delicacy of the rings when seen edgewise.
