Detector options were considered for the faint object camera of the NASA 2.4 m space telescope. Performance figures were recalculated for the most promising systems identified during previous studies. The systems are the following: I4-P four-stage magnetic focus intensifier, lens coupled to PbO vidicon; I2-EBS two stage magnetic focus intensifier, lens coupled to 25 mm or (40 mm EBS tube; C-I-EBS (40) proximity-focused converter, 40/40 electrostatic intensifier, 40 mm EBS tube (fiber optic coupled); C-I-EBS (25) proximity-focused converter, 40/25 demagnifying electrostatic intensifier, 25 mm EBS tube (fiber optic coupled); and MCPw-P wafer MCP intensifier (curved channel MCP) lens coupled to PbO vidicon. The 12-EBS option was selected. The detector head unit is dealt with and the electronics is discussed.
