Steve's Notes

===== NGC 450 48" (10/22/11): at 610x this double system is dominated by NGC 450, which appeared bright, large, 2.3' diameter. Sharply concentrated with a relatively large 30" bright core, surrounded by a very large, low surface brightness halo. The halo is slightly asymmetric and more extensive on the west side. Three faint "stars" are superimposed on the east side of the galaxy; two appeared stellar, but the faintest and most westerly object was clearly "soft" at 610x. These are apparently HII knots in the galaxy and the southeast object is listed in NED as UM 311 from the University of Michigan Emission Line Survey. NGC 450 has a very close companion, UGC 807, which is attached at the northeast side of the halo, 1.4' between centers. UGC 807 appeared fairly faint, fairly small, elongated 5:2 SW-NE, 0.7'x0.3', even surface brightness except for a very small brighter nucleus. Despite the fact that UGC 807 appears to form a double system, the companion has a redshift that is over 6x greater than NGC 450, so they are a line-of-sight pair. 13.1" (9/3/86): very large, diffuse, broad concentration, slightly elongated. Located 12.5' NE of 38 Ceti.
