NGC/IC Objects

IC 10: Galaxy (Cassiopeia) RA: 00h 20.3m / DEC: +59° 18'.1
Instrument: 18-inch Obsession

There are some three dozen galaxies that have been identified as members of the Local Group. These, our companion travellers through the cosmos, are often challenging targets in amateur telescopes. IC 10 is one such Local Group galaxy. The 18-inch Obsesion at 109X resolves a granular, salty oval with a handful of faint stars piercing the mist. Its 10.4 magnitude haze is spread over a 4'x2' area. The resulting surface brightness of 22.8 magnitude per square arcsecond makes this irregular barred galaxy a challenging quest in anything less than very dark skies. The trio of bright stars south of IC 10 range from magnitude 10.3 to 10.8 in brightness. Another 46 stars frame the view. You'll find this neighboring metropolis about 1.4 degrees due east of 2.3 magnitude Beta Cassiopeiae.
