SCORPIO at the 6-m telescope: current state and perspectivies for   spectroscopy of galactic and extragalactic objects
  A significant part of observations by Russian 6-m telescope is carried out using SCORPIO multi-mode focal reducer. A lot of scientific data have been collected using observations in direct imaging, slit spectroscopy and Fabry-Perot interferometry modes during the past ten years. Some results of these observations are considered in this review. We are also present a short description of a new generation instrument named SCORPIO-2.
