Galaxies for Fun Astronomical CCD photos on peculiar galaxies and other astronomical stuff.
There is an immense number of galaxies in an immense number of clusters out there. The closest clusters are hundreds of millions of lightyears away, so they are pretty dim, The individual galaxies are typically dimmer than magnitude 15 and beyond, so deep exposures are needed. Anyhow, one can observe several of the closest clusters with modest instruments.
