NGC 100: Edge-on Galaxy (Pisces) RA: 00h 24.1m / DEC: +16° 29'.1
Instrument: 18-inch Obsession

NGC 100 is a low surface brightness edge-on galaxy in Pisces. The nearest bright star is 2.8 magnitude Algenib, Gamma (88) Pegasi, some 3 degrees to the east-northeast. My drawing captures a 199X view in the 18-inch Obsession. NGC 100 is the 5' by 0'.6 grey smudge near the center of the field. It runs northeast to southwest, a 15th magnitude star marking the southwest extreme and a couple of equally faint embers at the northeast tip. NGC 100 is somewhat fatter in the middle; evidence, perhaps, of a galactic buldge. With a visual magnitude of 13.3, this Scd-type spiral has a meager surface brightness of 23.4 magnitudes per square arcsecond. It's a delicate, gauzy patch even in the big Dobsonian. Nineteen stars frame the view.
