Abstract

The William Herschel Telescope is a 4.2 m altazimuth design which has been in operation since 1987. The architecture of its control system is briefly outlined, and measurements of pointing, tracking, and field rotation are presented. Recent developments, including accurate algorithms for offset guiding, correction of errors due to refracting optics, and automation of the acquisition procedure, are described.
