Cherenkov mirror telescope SHALON-1 created at Leb edev Physical Institute and stated at 1991-1992 y. at Tien-Shan mountains 3338 m high above the sea level with 11,2 m2 mirror area and image matrix consisting of 144 photomultipliers with total viewing angle of 8o during 1992-2003 y. was used for observations of galactic sources: Crab Nebula, Cygnus X-3 Ticho Brage, Geminga and metagalactic sources: Markarian 421, Markarian 501, NGC 1275, 3C454.3, 1739+522. Timing analysis show that the contribution of protons of cosmic rays in observable gamma-quanta with energy more than 0.8TeV from the point sources of gammaquanta very high energies do not exceed 10% 15%. The fluxes at energy above 0.8TeV of observation Cygnus X-3 (4.20 ± 0.70) • 10-13 cm-2 s-1 is and Crab Nebula (1.10 ± 0.13) • 10-12 cm-2 s-1 . The observable energy distribution of gamma quanta in an interval of energy 1012 - 5 • 1013 from the local sources in our Galaxy do not contradict with the spectrum of Cygnus X-3 dF /dEγ ˜ Eγ 2.20±0.14 ,- of Crab Nebula -dF /dEγ ˜ Eγ 2.45±0.04 . The observed spectra of the gamma- quanta including the 10%-15% contribution of the proton showers is for Cygnus dF /dE ˜ E -2.51±0.22 , for Crab Nebula dF /dE ˜ E -2.61±0.04 . The images of Cygnus X-3 and Crab Nebula are also presented. One of the basic science parts is nuclear physics, physics of elementary particles and connected with them astrophysics and cosmology, studied the matter structure on micro and macro scales. The gamma-astronomy is a unique experimental possibility of high-energy cosmic rays sources (1012 - 1014 eV) location now. Only neutrino-astronomy will complete search and investigation of galactic and metagalactic objects where the protons and nuclei acceleration processes, accompanying with generation of non scattering by Universal magnetic fields gammas and neutrinos. The cosmological processes, connecting the physic of matter structure with its superdense quasistable state in active galactic nuclei will be observable on energy spectrum of electromagnetic radiation or, perhaps,
