As a result of development of image slicers, polarization analyzers and reduction technique, the limiting magnitude of spectral observations at BTA with high spectral resolution (up to R=80000) has been increased by 3 times, the limiting magnitude of spectropolarimetric observations increased from 3 to 8 times (in the red and UV ranges, respectively).
A wide-angle system (18x20 degrees) of high time resolution (up to 0.13s)
for real time detection of variable astronomical objects - optical
transients of gamma-bursts, flare stars and novae, supernovae at early
stages of their birth, and also near-earths moving bodies of natural and
artificial origin -is created.
In co-operation with Kosmoten and SRI RAS
