Paper Abstract

Limiting magnitude of A.O. reference stars is set by wavefront sensor intrinsic noise. Recently available avalanche intensified CCD detectors allow single photon event detection (photon counting) virtually free from readout noise. The paper describes a program started in spring 2002, aiming to use a Marconi L3CCD as a wavefront sensor for A.O.
