NGC925 is a bared galaxy positioned about 2 degrees east of gamma Tri that forms the base of the constellation of Triangulum. The galaxy has an expectedly large major axis of 10 arc minutes, but it's very dimmed so you might be needed fairly larger telescopes to appreciate the light of this minor outer galaxy. Although this picture hasn't been shown clearly, somehow you can see a bared structure stretched in east-west direction and two arms coiled up loosely. And there are several dots of nebulosities along the arms. The constellation of Triangulum is famous for a major galaxy of M33, but the compact galaxy of NGC925 is another scenic spot in this small constellation.
