Australian Cooke and Saturn


A Dark Transit of Titan

On November 5th / 6th 1907 Mr A B Cobham and Mr G D Hirst using a 4.5 inch Thomas Cooke & Son telescope 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.
