This is a small group of galaxies lurking 4.8 degrees SSE from κ Piscium, a star in the western part of the constellation. The largest galaxy IC 1501 can be seen at the bottom of the image, though it only has a diameter of 2.4 arc minutes. IC 1501 is a barred spiral galaxy with large star-forming regions, floating at a distance of approximately 240 million light-years. In the center of the image, lenticular galaxies such as NGC 7700 and NGC 7701 are located, forming a small galaxy group along with surrounding tiny galaxies.
