This
            absolutely magnificent field found in the constellation of Perseus
            contains the combination of cluster with blue reflection nebulosity
            of IC348 on the left side just below 3rd magnitude Omicron. on
            the right the dark nebula Barnard 3 is surrounded by the brick
            red nebulosity with no common designation. Just below IC348 is
            the dark streak of Barnard 4. This extremely deep image shows
            the extent of the background hydrogen to be present nearly everywhere.
