Based on the Rockwell International NICMOS3 HgCdTe array with 256 x 256 pixels. This camera provides a complete "turn-key" system with menu-driven software for image capture and display. The instrument contains a 6-position filter wheel and is cooled with liquid nitrogen.
First Light was obtained in June 1994.
