Paper Abstract

The Apache Point Observatory 3.5 meter altitude-azimuth telescope features lightweight honeycomb optics, a fast f/1.75 primary figure, multiple on-line instrument capability and a control system designed for efficient remote operation. Friction coupled rollers drive the axes and couple the encoders. We have concentrated particularly on reducing local seeing effects by controlling heat in the vicinity of the telescope. Measures include mass reduction, emissivity control, insulation and forced ventilation.
