About NGC 4382
NGC 4382 (M85) is catalogued as a lenticular (s0) galaxy in Coma Berenices. Its J2000 position is RA 12:25:24.11, Dec +18:11:29.4, corresponding to 186.3502 degrees RA and 18.1911 degrees Dec. The local catalogue places it about 60,000,000 light-years away. Its referenced angular extent is approximately 6.89 by 5.17 arcminutes.
Observing tips
StarWatchr rates this as a moderate target at magnitude 9.1. It is associated with spring observing, with midnight placement typically strongest around March. From 52 degrees north its theoretical meridian altitude is about 56.2 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 GiP. SIMBAD records the morphology as S0. A published radial velocity value is 769.5 km/s. The SIMBAD record currently connects it to 681 bibliographic references.
At roughly 6.9 arcminutes across, it benefits from a narrower field and adequate image scale. Use the listed 6.89 by 5.17 arcminute extent to check framing, and treat catalogue magnitude as integrated brightness rather than a direct measure of visual contrast.
