thesisposted on 2023-05-27, 08:27 authored by Boersma, Jan Ferdinand Jourke
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 3¬¨Œ©, 9, 25 and 60 arc min has yielded the excellent results of a limiting sensitivity of 13 vï¬¥ .7 and a resolution in the 3¬¨Œ© arc min. field of 1.4 arc sec. Some proposals are discussed to push these limits even further.
