During last two years (1988-1990) nineteen galaxies with megamaser emission have been observed in optical and radio wavelengths. Prime photographies of megamaser galaxies were obtained on 2.6m telescope of Byurakan Observatory. Spectral observations were carried out on 6m telescope of Special Astrophysical Observatory. Radio continuum observations at 3950 MHz have been done on the RATAN-600 radio telescope. Spectrogrammes of the galaxies were obtained with 1000 cannal one dimension scanner and in a few cases with two dimension scanner.
