About Perseus A
Perseus A (C24) is catalogued as a galaxy in Perseus. Its J2000 position is RA 03:19:48, Dec +41:30:42, corresponding to 49.9507 degrees RA and 41.5117 degrees Dec. The local catalogue places it about 230,000,000 light-years away. Its referenced angular extent is approximately 2.63 by 1.78 arcminutes.
Observing tips
StarWatchr rates this as a very hard target at magnitude 11.9. It is associated with winter observing, with midnight placement typically strongest around November. From 52 degrees north its theoretical meridian altitude is about 79.5 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 Bla. SIMBAD records the morphology as cD. A published radial velocity value is 4998.1 km/s. The SIMBAD record currently connects it to 4285 bibliographic references.
At roughly 2.6 arcminutes across, it benefits from a narrower field and adequate image scale. Use the listed 2.63 by 1.78 arcminute extent to check framing, and treat catalogue magnitude as integrated brightness rather than a direct measure of visual contrast.
