Scientific paper

The pointing of a telescope on a certain celestial object is achieved when the object is acquired in the field of view of the telescope and on the centre of a cross-wire system or any marking that indicates the centre of this field. Star acquisition with the 3.6 m telescope is computer-controlled. However, the behaviour of the telescope, mainly concerning f1exures in the telescope structure, misalignments in the telescope axes and optics, must be known in detail. To find the different contributions to the total pointing error, a pointing programme was developed at the Anglo-Australian Observatory by P. Wallace for the pointing of the Anglo-Australian telescope, and this programme was made available to the author, thanks to Donald Morton, Director of the AAO, and P. Wallace.
