If your paper based on SCORPIO observations, we would appreciate the following citation of the main paper with description of the device: Afanasiev V.L. & Moiseev A.V., 2005, PaZh, 31, 214 (Russian PDF); English translation: 2005, Astronomy Letters, 31, 194 ( English PDF ).
Thank you!

The optical part contains of the collimator (F/2.2) and the camera (F/1.8). The total focal ratio it the prime focus of the telescope is (F/2.6). The optics of the reducer compensate for the aberrations of the main mirror of the telescope, all optical surfaces have antireflecting coating in a spectral range 3500-10000 A. SCORPIO has two filter's wheels for interferometric narrow-band and middle-band filters (Wheel 1 in the focal plane) and for broad-band filters (Wheel 2 between the field lens and the collimator). The dispersers (grisms or Queensgate IFPs ET-50) installed between the collimator and the camera where the exit pupil of the optical system is located. The diameter of the collimated beam is 35mm.

The first light on 6m telescope was taken 21 September 2000. The similar device (without adapter) was constructed by us for 2.6m telescope in the Byurakan (Armenia).
