An easy *tight* group which forms the S vertex of a triangle with the two
"club" stars (xi and nu) in Orion. (Note that this trio, including the
club stars and the cluster, are easily mistaken in the binocs for nearby
134 and 133 Tauri to the NW, and the little clump of stars around HD
39880!) The OC is connected with xi and nu Ori by faint streamers of
resolved and unresolved stars. One pretty pair of mag. 6 stars to the E
points directly at the direct vision "haze" of NGC 2169.  Within this
"haze", a steady hand will show at least 3 or 4 "concentrations" or stars
embedded. These clumps all appear to be stellar mag. 5 or 6. Pretty!
