Photometer with the tunable filter for medium-sized telescopes
The Mapper of Narrow Galaxy Lines (MaNGaL) has been developed and
manufactured. The instrument, the principle of operation of which
is based on the use of the Fabry-Perot interferometer, allows us to
obtain monochromatic images of galactic and extragalactic objects
in different emission lines of ionized gas. It was successfully tested
at the 1-m SAO RAS telescope and 2.5-m telescope of the Caucasian
Mountain Observatory of SAI MSU.

New radiometric complex at RATAN-600 to observe fast radio bursts
A new radiometric complex for the range of 4.7 GHz has been developed
and implemented at the RATAN-600 telescope of SAO RAS. The complex is
designed for observations of fast radio bursts in the mode of the
twenty-four-hour automatic sky survey. The standard radio survey
of objects falling within the field of view is conducted simultaneously.
The radiometric complex includes: 4 radiometers with the 600-MHz common
band and division of the common band into 4 "narrow" contiguous subbands
of 150 MHz each. The construction given allows one to reliably detect
fast bursts from the outer space and separate them from local radio
noise basing on radio wave dispersion in the interstellar medium.
