Aerodynamic and Thermal Problems Around and Inside a Dome and Telescopeadvantage of local atmospheric conditions. With the new 2-meter reflector, specifically intended for high resolution imaging, the concept has been, ideally, to separate three air-masses: outside, inside the tube, and inside the dome. As a first step, no parallel plate of required size and quality be

Information Efficiencies of Telescopes and their Instrumentationtem of light receiving and recording equipment, including the conditions of observation. The proposed method for calculating this information efficiency relies on the analysis of the output observational material and not on the characteristics of optical and electronic components of the instrumentat

The benefits to be gained from increased aperture size, however, are only utilised effectively if efficient instrumentation is also available. There have been significant improvements recently in this area, part icularly in detector technology

A 6-Metre Polar-Viewing Telescopelon. Object tracking is then performed by rotation of the detector around the point which represents the “image” of the celestial pole. In particular, the polar axis may coincide with the optical axis of the system.

Design of the 4.2 M Herschel Telescope and Instrumentss the William Herschel Telescope, is fully designed and manufacture has begun. It is due for completion in the mid-1980’8. The telescope, dome and instrument design have all interacted with one another, particularly in the search for economy. Among the proposed instruments is a novel collimator-less spectrograph.
