NGC 5471
18" (6/28/03): highest surface brightness of any of the HII regions in M101. Appears very similar to a small, elliptical galaxy -- even contains a small, brighter core. Situated beyond the main glow of the galaxy, 11.5' NE of the core of M101.
18" (6/21/03): at 323x appears similar to a compact, round galaxy. Furthest NE of all the HII regions and well separated from the main glow of M101. Interestingly, this was one of the few HII regions that displayed a positive contrast response to a UHC filter at 161x and 215x.
17.5" (6/7/97): this is one of brightest HII regions in M101, on the extreme NE end of the galaxy 11.5' from center. Appears as a moderately bright knot, ~20" diameter. This HII region stands out well due to its isolation and fairly high surface brightness with crisp halo. Incorrectly identified as a galaxy in the MCG.
