Abstract
The autoguiding of ground-based telescopes has developed relatively slowly over the last thirty years or so, in spite of the existence of exceedingly sensitive photoelectric detectors. Of those based on the mechanical chopping or dissection of the light in a stellar image, there are essentially three types. The first (Ref. 1) entails division of the light at the roof of a right-angled prism or the apex of a pyramid, the second, a rotating knife-edge (Ref. 2), and the third, an elegant development of the latter (Ref. 3), uses a ball bearing rotating inside an annulus.
