The analysis of results of observation of extensive air showers at height of 3338 m above the sea level by means of gamma-telescope SHALON at the zenith angles 72o , 76o, 84o , 96o are presented. The observation results are compared with the data of detection of showers according to the direction into the zenith. The observation has been carried out at high mountainous Tien -Shan station (3338 m) with SHALON -1 gamma-telescope functioning since 1992 and with coming into operation SHALON-2. The SHALON mirror telescopic system consists of composed mirror with area of 11.2m2 . It is equipp ed with 144 photomultipliers lightreceiver with 0.5o angular resolution, that has the most in the world angular size 8o . It allows to control the background of cosmic ray particle emission and the atmospheric transparency continuously with observation that means the increasing of observation efficiency. So it is the telescope characteristics that permit to start the search of local neutrino sources with energy 1012 - 1015 eV on EAS generating in mountain-range located at some 5 and more kilometers from gamma-telescope (in Russian the abbreviation SHALON means the Extensive Air Showers from Neutrino) The gamma-sources search is the first step of the astronomy to the very high energy range. Only neutrino astronomy in the future can complete the search and investigation of galactic and metagalactic objects where the proton and nuclei processes are realized. These processes accompanied by generation of gamma-quanta and neutrino witch are not scattered in Universe magnetic field, that gives an addition possibilities of investigation of the properties of active stelar objects at a very high energy. The observations are carried out on P.N. Leb edev Physical Institute Tien -Shan high-mountainous station with gamma-telescope SHALON-1 acting since a 1992 and started operating SHALON-2 [1-6]. The SHALON telescopes feature is the large full angle that enlarges the observation area, increases the statistical
