About Triangulum Galaxy
Triangulum Galaxy (M33) is catalogued as a spiral galaxy in Triangulum. Its J2000 position is RA 01:33:50.89, Dec +30:39:36.8, corresponding to 23.4621 degrees RA and 30.6602 degrees Dec. The local catalogue places it about 3,000,000 light-years away. Its referenced angular extent is approximately 60.26 by 35.48 arcminutes.
Observing tips
StarWatchr rates this as a hard target at magnitude 5.7. It is associated with autumn observing, with midnight placement typically strongest around October. From 52 degrees north its theoretical meridian altitude is about 68.7 degrees; local horizons and the live altitude chart determine the practical window.
Its brightness makes it a practical binocular or small-telescope candidate when it is well above the horizon.
What to expect
The SIMBAD classification for the matched source is GiG. SIMBAD records the morphology as SA(s)cd. A published radial velocity value is -179.2 km/s. The SIMBAD record currently connects it to 6280 bibliographic references.
At roughly 60.3 arcminutes across, it favors a wide-field imaging setup. Use the listed 60.26 by 35.48 arcminute extent to check framing, and treat catalogue magnitude as integrated brightness rather than a direct measure of visual contrast.
