The Perseus galaxy cluster (Abell 426) is about 250 million light-years from our galaxy and contains more that 500 catalogued galaxies. The brightest member is NGC 1275, near the left edge of the image, at magnitude 11.6. NGC 1275 is a strong source of radio waves and x-rays.

Abell 426 is the dominant member of the Perseus-Pisces supercluster. The super cluster extends to 300 million light-years and covers 40 degrees of the winter sky.
