Abstract

A four field television star acquisition and guiding system
incorporating image intensification has been designed,
constructed and evaluated. The system which includes a 152mm
objective, a three stage cascaded electrostatic image intensifier,
a newvicon target low light level television camera is mounted
on the 1.04 metre reflecting telescope of the Canopus Hill
Observatory near Hobart.
An extensive testing programme on fields of 3½, 9, 25 and 60
arc min has yielded the excellent results of a limiting sensitivity
of 13 ͫ .7 and a resolution in the 3½ arc min. field of 1.4 arc sec.
Some proposals are discussed to push these limits even further.
