Corwin's Notes

===== NGC 4395. See NGC 4399 which, along with NGC 4400 and NGC 4401, are HII regions in NGC 4395.

Steve's Notes

===== NGC 4395 17.5" (5/15/99): this chaotic galaxy is dominated by several bright HII regions. At 100x, the large low surface brightness glow is clearly clumpy with a couple of faint knots evident on the east side of the haze. At 220x, the glow of the galaxy is more difficult to view and several nonstellar knots and a couple of very faint superimposed stars are more prominent. The brightest HII region is NGC 4401 located 2' SE of the core, ~25" in size, with a second smaller 15" knot (NGC 4400) close south. The core of the galaxy appears as an ill-defined, low surface brightness glow, larger than the individual HII knots. A mag 14.5 star is superimposed NE of the core. On the SW side of the core is a third difficult knot, about 15" in diameter (NGC 4399) requiring averted vision to confirm. Member of the M94 Group (CVn I Cloud). 17.5": faint, very large, extremely low surface brightness, must use low magnification to view. Three knots are involved (one of these observed "knots" may be the core) within a very diffuse glow. The brightest knot (NGC 4401) is at the SE end about 2' SE of center with NGC 4400 close SSW of NGC 4401. A mag 14.5 star is at the north end. Also see description for NGC 4399. 13" (4/12/86): at 62x appears very large, diffuse, slightly elongated glow, broad very weak concentration.
