Abstract
We have visually examined 12 Palomar red plates for galaxies at low Ga lactic latitude b, where the Supergalactic Plane (SGP) is crossed by t he Galactic Plane (GP), at Galactic longitude l similar to 135 degrees . The catalogue consists of 2575 galaxy candidates, of which 462 have major axis diameter d greater than or equal to 0.8 arcmin (uncorrected for extinction). Galaxy candidates can be identified down to \b\ appr oximate to 0 degrees. One of our galaxy candidates (J24 = Dwingeloo 1) has recently been discovered independently at 21 cm by Kraan-Korteweg et al. as a nearby galaxy Comparisons with the structures seen in the IRAS and UGC catalogues are made, We compare the success rate of iden tifying galaxies using the IRAS Point Source Catalogue under different colour selection criteria. The criteria that require both the 60- and 100-mu m fluxes to be of high quality have the highest probability of selecting a galaxy (with d greater than or equal to 0.6 arcmin), but at the expense of selecting a smaller number of galaxies in total.
