About NGC 4569
NGC 4569 (M90) is catalogued as a spiral galaxy in Virgo. Its J2000 position is RA 12:36:49.79, Dec +13:09:46.6, corresponding to 189.2075 degrees RA and 13.1629 degrees Dec. The local catalogue places it about 60,000,000 light-years away. Its referenced angular extent is approximately 9.6 by 3.93 arcminutes.
Observing tips
StarWatchr rates this as a hard target at magnitude 9.5. It is associated with spring observing, with midnight placement typically strongest around March. From 52 degrees north its theoretical meridian altitude is about 51.2 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 Sy2. SIMBAD records the morphology as S_AB. A published radial velocity value is -199 km/s. The SIMBAD record currently connects it to 957 bibliographic references.
At roughly 9.6 arcminutes across, it benefits from a narrower field and adequate image scale. Use the listed 9.6 by 3.93 arcminute extent to check framing, and treat catalogue magnitude as integrated brightness rather than a direct measure of visual contrast.
