Overshadowed by its brighter and more famous neighbor M33, this smaller but more structured spiral in Triangulum should not be overlooked on your next observing session. Listed at magnitude 10.7 and 10 arc minutes in size, this SAB spiral is low surface brightness, but boasts a few nice pink HII regions in this image for inspection. The yellow barred core extends out to a pair of blue arms, studded with bright knots from OB associations. Many other faint galaxies can also be found in this field on the larger image.
