NGC 247: Spiral Galaxy (Cetus) RA: 00h 47.1m / DEC: -20° 45'.6 Instrument: 10-inch Starfinder |
NGC 247 is a large, low surface brightness galaxy in Cetus. It's located about 3 degrees south-southeast from 2.0 magnitude Diphda, Beta Ceti. The galaxy's integrated visual magnitude is 9.1 but its surface brightness is only 23.0 magnitude per square arc second. This combined with its southerly declination make NGC 247 a challenging object from observing sites at mid-northern latitudes. My drawing is based on a 63X view in the 10-inch Starfinder equatorial. It shows a 14'x4' oval with a pair of 12th magnitude stars near the southern tip. The galaxy is elongated along a north-south axis. |
