ИСТИНА

A briefly review of the history of the investigations of multi-spin and related phenomenons at the Russian 6-m telescope is presented. Different types of kinematically decoupled systems were studied since the first years of telescope operation: interacting galaxies, external polar rings and circumnuclear polar and inclined discs, counter-rotated systems, warps and tidally-induced filaments. The evolution of observational technique is also considered, from the first long-slit spectrographs to different 3D spectroscopic devices.
