Description
In this report we present results of multi-wavelength investigations of brights blazars sample provided mainly with SAO RAS optical telescopes - 6-meter reflector and 1-meter class instruments. The campaign of optical monitoring spans over 20 years. The sample consists of almost two dozens sources in wide brightness range (optical R band) - between 14th and 20th magnitudes. The statistical analysis of some selected blazars light curves in optical range, being combined with radio and high-energy emission data revealed new features of non-stationary events in Active Nuclei. Spectral studies with 6 meter BTA telescope gave some findings concerning internal structure of blazars and matter localized on line-of-sight. The typical flux variation times gave estimates of emission zones size for individual objects.
