Using the NPB filter, LHA 120-N 138C was also seen 1.8' W as a very faint, fairly small, 25" glow. It surrounds a mag 15.2 star that was not seen with the filter. Much brighter is N 138B, located 5.2' SW of NGC 1949. With the filter it appeared fairly bright, small, round, 20" diameter, crisp-edged. A mag 15 star is attached at the southwest edge. This interesting field is located 14' NW of mag 6.1 HD 36584 (equal mag 1.3" pair).

John Herschel discovered NGC 1949 = h2857 on 30 Dec 1836 and recorded "pB; S; R; psbM; 20"." His position (single sweep) is accurate and appears to described the small, high surface brightness nebula only.

600/800mm - 30" (10/15/15 - OzSky): very bright, fairly small, round, high surface brightness, ~35" diameter. No resolution, though this is primarily an emission nebula. A string of 3 mag 13.7/12.8/13 stars extend to the southwest by 45", 2.2' and 3.4'. I was very surprised when I added an NPB filter at 152x. A fairly prominent, large (~1.3' diameter), round emission nebula was nearly attached on the southwest side! This nebula (considered part of LHA 120-N 138A) surrounds a mag 13.6 star at its center and has a slightly brighter rim. Together with NGC 1949 the pair nearly forms a "diamond ring".
