About NGC 247

NGC 247 (C62) is catalogued as a galaxy in Cetus. Its J2000 position is RA 00:47:08, Dec -20:45:37, corresponding to 11.7856 degrees RA and -20.7604 degrees Dec. The local catalogue places it about 6,800,000 light-years away. Its referenced angular extent is approximately 17.02 by 5.98 arcminutes.

Observing tips

StarWatchr rates this as a hard target at magnitude 9.1. It is associated with autumn observing, with midnight placement typically strongest around September. From 52 degrees north its theoretical meridian altitude is about 17.2 degrees; local horizons and the live altitude chart determine the practical window.

Because it is faint, use a larger aperture where possible, avoid bright Moon conditions, and use averted vision.

What to expect

The SIMBAD classification for the matched source is LSB. SIMBAD records the morphology as SAB(s)d. A published radial velocity value is 162 km/s. The SIMBAD record currently connects it to 484 bibliographic references.

At roughly 17 arcminutes across, it benefits from a narrower field and adequate image scale. Use the listed 17.02 by 5.98 arcminute extent to check framing, and treat catalogue magnitude as integrated brightness rather than a direct measure of visual contrast.
