Abstract
The paper describes an improved spectrograph of the Cassegrain focus of the 2 m ShAO reflector using a CCD camera. The classic Universal Astro Grid Spectrograph (UAGS) was adapted to use the Andor CCD camera to obtain spectra of objects with low brightness in the range of 3600–8000 Å. A spectrograph with a diffraction grating of 651 line/mm makes it possible to obtain the spectra of stars on the 2 m ShAO telescope up to 18 mag with a resolution of 1200, with a signal-to-noise ratio of about 50 for half an hour of exposure. The maximum allowable resolution is R = 3400 with binning 1 × 1. The complex can be used for observations of various types of transient objects, variable stars, and extragalactic objects.
