[en] The long-term studies of the Cygnus Region at energies 800 GeV - 100 TeV by SHALON telescope are presented in this paper. The results of twenty-year-long observations of the Cyg X-3 binary at energies 800 GeV - 85 TeV, detected by SHALON in 1995y are presented with images and integral spectra. The 4.8 hour orbital modulation of TeV γ-ray emission of Cyg X-3 was found in SHALON data. A number of high activity period of Cyg X-3 were detected at energies > 800 GeV during the all observation time. The correlation soft X-ray and TeV energy γ-ray fluxes is traced. Additional to Cyg X-3 study data on the TeV sources of Cygnus Region, namely γCygni SNR was obtained with SHALON. (paper)
