This image captures small galaxies located 5.7 degrees south of the γPsc in the westernmost part of the constellation. On the right side of the image, you can see an elliptical galaxy NGC7556 with a size of 2.4 arc minutes and a brightness of 12th magnitude. On the left is the spiral galaxy NGC 7566 with an active galactic nucleus, approximately 2 arc minutes in size and with a brightness of 14th magnitude. These galaxies are located 340 to 360 million light-years from the Milky Way Galaxy and form a small galaxy group together with nearby small galaxies.
