NGC 7331 and Stephan's Quintet, Pegasus

Pegasus is located in the far northern skies from southern Australia and well away from the galactic plane making imaging of deep sky objects, such as galaxies, more challenging. The challenge is worth it as demonstrated by the image below. Not only is the field full of Milky Way stars, but there also are numerous galaxies, both near and far (in relative terms), to be found there. Dominating the field is NGC 7331, an obliquely-angled galaxy roughly 40 million light years away that is clearly spiral, displaying a core of old yellow stars, a disk of young blue stars and star clusters, and lanes of dark dust best seen on the edge closest to us. Above NGC 7331 are several other galaxies (NGC 7335, 7336, 7337 and 7340) which, together with NGC 7331, comprise the so-called "NGC 7331 Group" of galaxies, though the "grouping" is visual only as the smaller galaxies lie roughly 300-350 million light years away from us. 

To the left of the field is the tight grouping of five galaxies known as "Stephan's Quintet". It was the first compact galaxy group to be discovered (by E. Stephan at Marseille Observatory in 1877), and remains the most widely studied grouping in the entire sky. The four (yellowish) galaxies are physically connected and form a true galaxy group (Hickson Compact Group 92); three of them, through their mutual gravitational interactions, are very distorted and display tidal trails, and will eventually merge into single galaxy in the distant future. The four galaxies of the group lie 210-340 million light years away, while the uppermost galaxy, bluish NGC 7320, is actually a foreground object lying about 39 million light years away from us, making it a possible member of the NGC 7331 Group. 

Under close inspection, many more distant "fuzzies" may be found in the field. A most interesting field indeed.
