The new galactic gamma-source (neutron star) 2129+47XR is detected at energy >0.8 TeV with flux (0.19±0.09)x10^-12 cm^2s^-1 and indices of the integral spectra are kγ=−1.12±0.06, kON=−1.28±0.07 and kOff=−1.73±0.07. The results of ten-year observation of galactic source Cygnus X-3 by SHALON mirror Cherenkov telescope are discussed. The gamma -quantum spectra and images of the sources are presented. The Cygnus X-3 binary, known for more than 20 years as a source with variable intensity have been regularly observed since a 1995. The the increase of gamma-quantum flux was observed in 1997 and 2003 years.
