We discuss some results of the observation gamma-quanta sources Geminga and Tycho's SNR and the discrimination methods between gamma-rays and protons.I_(Geminga)=(0.48 +-0.17)centre dot 10~(-12)cm~(-2)s~(-1)and I_(Tycho)=(1.89 +-0.56)centre dot 10~(13)cm~(-2)s~(-1).Selection of showers produced by gamma-quanta from background has made according the following criteria 1)a < 20deg;2)length/width> 1.6;3)intO> 0.6;4)intl> 0.8;5)distance is < 3.5.The experimental distributions of image parameters on used criteria are presented.The time analysis of observation data on NGC 1275,Mkn 501,Crab Nebula,Cygnus X-3 has shown that the contribution of cosmic ray background into observable gamma-quanta does not exceed-10-15%.The obtained Tycho's spectrum compares with theoretical predictions.
