Steve's Notes

NGC 100
48" (11/8/15): bright, extremely large and thin edge-on 10:1 WSW-ENE, extends at least 4.0'x0.4'. A brighter central region extends ~2' in length and the outer extensions fade significantly and taper towards the tips as they dim out. A mag 15.3 star is just beyond the east end of the galaxy. Four mag 15.2-16.2 stars (in an E-W string) lie within 2.5' south of the galaxy.
PGC 1509358 is just south of the southwestern tip of the galaxy. At 488x it appeared very faint (V = 17.2), very small, slightly elongated, ~10"x7". With careful averted vision, I could just hold the galaxy continuously. A fairly difficult mag 17+ star is 30" SW. The redshift based light-travel time (based on z = .10) is 1.2 billion years.
17.5" (10/8/88): very faint, thin edge-on 7:1 WSW-ENE, moderately large, 2.0'x0.3', weak concentration. NGC 99 lies 42' S.
