About NGC 4449

NGC 4449 (C21) is catalogued as a galaxy in Canes Venatici. Its J2000 position is RA 12:28:11, Dec +44:05:40, corresponding to 187.0463 degrees RA and 44.0936 degrees Dec. The local catalogue places it about 10,000,000 light-years away. Its referenced angular extent is approximately 6.69 by 3.96 arcminutes.

Observing tips

StarWatchr rates this as a hard target at magnitude 9.4. It is associated with spring observing, with midnight placement typically strongest around March. From 52 degrees north its theoretical meridian altitude is about 82.1 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 EmG. SIMBAD records the morphology as IB. A published radial velocity value is 203.8 km/s. The SIMBAD record currently connects it to 1206 bibliographic references.

At roughly 6.7 arcminutes across, it benefits from a narrower field and adequate image scale. Use the listed 6.69 by 3.96 arcminute extent to check framing, and treat catalogue magnitude as integrated brightness rather than a direct measure of visual contrast.
