This image shows you two galaxies positioned about 3 degrees northeast of Mira, a famous variable star glittering at the neck of Cetus, right and left ones are NGC936 and NGC941, respectively. NGC936 is a barred galaxy with a dimmed elliptic light surrounding, has a size of a bit smaller than 5 arc minutes. Another one of NGC941, lying at about 10 arc minutes east from NGC936, is an indistinct spiral with a diameter of about 3 arc minutes. They're forming a small-scaled galaxy group with tiny companion galaxies, distance is about 60 million light years.
