There are a huge number of galaxies visible in this image. Some of them I've anotated on the image below:
Many of these galaxies are very faint; magnitude 17.5 or fainter, you can find out more info here,

if you're interested in this sort of thing.
The main member is ngc 1275 which Hubble recently imaged in superb detail;
antwrp.gsfc.nasa.gov/apod/ap080822.htmlNGC 1275 is the type SO galaxy at the center of this image of a portion of the Abell 426 galaxy cluster.
It is the dominant member of the Perseus Cluster of Galaxies and a strong radio source, therefore named Perseus A, and 3C 84 from its entry in the 3rd Cambridge Catalogue of Radio Sources. It is also a strong X-ray source. Its nucleus shows emission lines and is of Seyfert type 1 - this galaxy was in Carl Seyfert's original list of galaxies with peculiar emission lines in their nucleus, now called Seyfert galaxies. Filaments of gaseous material are moving explosively outward at 1500 miles per second. (SEDS)
My image is taken through my 10" Newtonian onto a SX H9C OSC camera - about 70 minutes of exposure.
