About NGC 2775

NGC 2775 (C48) is catalogued as a galaxy in Cancer. Its J2000 position is RA 09:10:20, Dec +07:02:00, corresponding to 137.5839 degrees RA and 7.038 degrees Dec. The local catalogue places it about 55,000,000 light-years away. Its referenced angular extent is approximately 4.86 by 3.91 arcminutes.

Observing tips

StarWatchr rates this as a very hard target at magnitude 10.4. It is associated with winter observing, with midnight placement typically strongest around February. From 52 degrees north its theoretical meridian altitude is about 45 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 AG?. SIMBAD records the morphology as SA. A published radial velocity value is 1375 km/s. The SIMBAD record currently connects it to 379 bibliographic references.

At roughly 4.9 arcminutes across, it benefits from a narrower field and adequate image scale. Use the listed 4.86 by 3.91 arcminute extent to check framing, and treat catalogue magnitude as integrated brightness rather than a direct measure of visual contrast.
