Abstract

This paper describes the construction and operation of a medium resolution spectrometer used in the visual wavelength range. It is homebuilt, but has built in guiding and calibration, is fully remote-operable, and operates at a resolution R = 3000. It features a fast f/3.5 system, which allows it to be used with a fast telescope (18-inch f/3.5) with no Barlow or other optical matching devices.
