A Search for Galaxies behind the Milky Way between L = 230(deg) and 250(deg)

This is the second paper concerning our systematic search for galaxies behind the Milky Way by means of film-copies of the UK Schmidt Southern Infrared Atlas at an effective wavelength of 790 nm. The present search was carried out by visual inspection of 14 films between l=232(deg) and 250(deg) at b=0(deg) covering 411 square degrees; a total of 4633 galaxies were detected with diameters greater than 0.1 arcmin. A catalog of the detected galaxies was made regarding position, size, galaxy type, and cross identification. Of the detected galaxies, 194 are given in the ESO galaxy catalog and 232 appear in the IRAS Point Source Catalog. More galaxies were detected at regions with less H I column densities in the Milky Way; the characteristics of the Galactic extinction are similar to those found in the first investigation between l=210(deg) and 230(deg) . A superposition of some clusters of galaxies is seen around l=240(deg) , b=4(deg) over ~ 15(deg) in angular size; the clusters are probably distributed from 50 to 350 Mpc. A nearby cluster of galaxies is also at a distance of about 35 Mpc around l=243(deg) and b=-6(deg) with an elongated structure nearly vertically against the galactic plane linking the Antlia cluster to the Lepus cloud.
