Abstract

The COAST group in the University of Cambridge have a lot of operational experience of using fast guiding systems to control the pointing of up to four separate telescopes simultaneously as well as a lot of operational experience of using array CCD systems and avalanche photodiode photon counting systems for signal detection. This paper looks at the advantages and disadvantages of these systems for fast guiding and wavefront sensing applications.
