The Richardson-Brealey Spectrograph (RBS) available at the f/15 Cassegrain focus of the 1.0-m JKT was built at the University Observatory, St Andrews from the original design by Richardson and Brealey ( Journal of the Royal Astronomical Society of Canada, vol 67, p165, 1973). It is an efficient, light-weight, robust and stable, off-axis spectrograph, intended primarily for low- to medium-resolution stellar spectroscopy. Having no computer-controlled components it is completely reliable, but grating angles etc must be set manually. The detector can be any of the standard JKT CCDs; users will notice some features provided for its original photographic use.
