Corwin's Notes

===== NGC 2113. It's a little difficult to know what position to take for this object. JH has five observations of it, in four of which he saw stars or described it as a cluster. The object on the DSSR2 image appears as a nebula about about 1.7 arcmin in diameter with stars involved, particularly on the eastern edge where the nebula narrows to an apex. It looks like there is a compact cluster embedded in this apex. I've given the position of the approximate geometrical center of the nebula as THE position for NGC 2113, but offer two others as well. One is for a star just east of the center, and the second is for the apex itself. Take whichever suits your thoughts on this object.

Steve's Notes

===== NGC 2113 30" (10/13/15 - OzSky): bright, fairly large elongated glow, knotty, 1' diameter. This nebulous cluster has an unusual structure; a small bright elongated knot in on the east end and a second small, fairly bright, elongated knot is adjacent on the west side. Strong response to an NPB filter and a much larger nebulous hazy glow extends to the west, increasing the size to 1.5'. The high surface brightness elongated pieces lie on the east end. Located 30' E of the NGC 2078/79/83/84 complex. Emission nebula LHa 120-N163 lies 12' W and appeared as a bright, large, irregular glow, ~3' diameter. Several stars are involved with the nebulosity, including a mag 13 star on the north side and a couple of additional mag 13.5 stars (H-S 400). Excellent response to the NPB filter at 152x and 303x. The glow is clearly brighter in an arc (opening towards the northwest) on the southeast end.
