===== NGC 3184 48" (4/4/11): NGC 3184 is a beautiful face-on spiral with two main long arms and branches, along with several HII knots (two with NGC designations) in the arms. Contains a relatively small, very bright core, ~1' diameter with a sharp stellar nucleus. A mag 15-16 star is visible about 40" NE of the center near the edge of the core. One arm is attached on the east side of the core and winds counterclockwise around the south side of the core towards the west. The outer halo of the galaxy to the south of this arm has a much lower surface brightness. NGC 3181 is a bright, 15" knot (HII region/massive star cluster) embedded in this arm, 1.2' SW of the nucleus. The arm then continues spiraling outward as it heads north and contains NGC 3180, very small knot with a stellar core at 1.8' NW of the nucleus. This small knot is within a larger, slightly brighter portion of the arm. A second prominent arm is attached on the west side of the core and rotates counterclockwise around the north side towards the east. The surface brightness lowers on the east side and the arm splits into two branches. A mag 11.7 star is superimposed near the outer edge on the north side beyond the arm. Located 11' ESE of mag 6.6 HD 89053. 17.5" (4/4/92): fairly bright, large, slightly elongated ~N-S, large 4' halo has a fairly low surface brightness, very weak concentration, small brighter elongated core. A mag 11.5 star is at the north edge of the halo 1.8' from the center. There is an impression of spiral structure thought it was not distinct. Located 40' W of Mu Ursa Majoris (V = 3.1).
