Steve's Notes

===== NGC 1042 48" (10/26/16): at 488x; bright, very large, face-on spiral with a small bright core and a relatively small weak bar oreinted ~NW-SE. Low contrast spiral structure is visible around the core. Most prominent, though, is an outer spiral arm along the east side sweeping N-S in a gentle arc and brightest just to the west of a mag 13.6 star [SDSS reveals numerous HII knots] situated 1.6' SE of the core. The outer spiral arm along the western edge is more diffuse and ill-defined, passing just east of a 16th magnitude star 1.7' WSW of the core. 17.5" (11/1/86): very large, very diffuse low surface brightness system best viewed at 83x or 133x. Almost round, slightly brighter on the SE end with either a very faint star(s) superimposed or a brighter knot. Forms a pair with NGC 1048 (double system) 6' SSE and NGC 1052 lies 14' NE. 13" (9/3/86): very large but diffuse, only a very weak concentration. 13" (9/9/83): large, very diffuse, no central brightening, irregularly round, best at 62x (too large and diffuse for higher power).
