Abstract

We report on a new survey for low surface brightness galaxies using Kodak Tech Pan 4415 film on the UKST, and demonstrate the advantages of this film over conventional IIIa plates when searching for faint, extended objects. Recent experiments with films of the Virgo cluster have shown that the noise per pixel in deep exposures is only 0.7 % of sky, enabling known objects to be traced out to an isophote around 27 Rµ. In addition, a preliminary survey has revealed several new galaxies with central surface brightnesses around 24 Rµ. With the digital coaddition of several films, we expect to be able to measure objects out to the 28 Rµ isophote and detect galaxies with central surface brightnesses as faint as ∼ 25 Rµ, i.e. below 3 % of sky.
