Except for the bright star at the lower right, most of the objects in this image are galaxies. The large ellipical at upper right is NGC4874, with NGC4889 at upper left. These two galaxies are a binary pair, each with numerous associated smaller galaxies.
If you click on the half-size image above, you will jump to the full-size image page. In this case I have also included an equivalent Digitized Sky Image for comparison.
I took this picture in New Mexico.
