,A study of galaxies with ,≤0.3 in the ESO/SRC Atlas Field No. 411: Galaxy distribution and luminosidges of galaxies, constituting a filament of length > 20 ..Mpc. Luminosity functions are calculated for the high and low density regions. The fraction of bright galaxies is higher for the high density region.

On the orientation of double galaxies,angle is 0° – 180°. The distribution of the .-angle is highly non-random. There is a statistically significant excess of small absolute values of the .-angle and a deficit near perpendicular configurations.

A search for homogeneous samples of quasars, magnitude range 18. – 19. 600 quasar candidates were found. Redshifts were determined from the low-dispersion objective prism spectra for 255 of these objects. The spatial distribution of 158 Ly . quasars is discussed.
