Electronic Systems for Short-Exposure Photography of Celestial Objects,Optical instability of the earth’s atmosphere impairs the quality of photographs of astronomical objects. One method of improving image quality is to photograph during periods of relative atmospheric quiet.

Atmospheric Transmittance and the Interrelationships of Certain Optical Parameters,Studies of atmospheric transmittance and scattered-light intensity make it possible to establish relationships among certain optical parameters. These relationships can then be used in solving a number of applied problems.

Monitoring the Optical Stability of the Atmosphere for Small and Large Optical Thicknesses,The brightness of the sky on the solar almucantar is chiefly determined by the following parameters : the solar zenith distance z., the optical thickness of the atmosphere .. and the albedo of the underlying surface q, and it is greatly dependent upon the form of the scattering indicatrix.

Short Method for Determination of Atmospheric Transmission Coefficients, of these coefficients by the well-known “long” method of Bouguer entails rather large expenditures of time. Moreover, this method gives accurate values only for an optically stable atmosphere. There is therefore a need for “short” methods.

Erstes Kapitel Stetige Konvergenzstronomical Observatory of the Academy of Sciences of the USSR. Some possibilities for using photoelectric and television methods to combat noise have already been considered . To determine certain fundamental conditions for the design of a television noise compensator, however, it was necessa
