About Crab Nebula
Crab Nebula (M1) is catalogued as a supernova remnant in Taurus. Its J2000 position is RA 05:34:31.97, Dec +22:00:52.1, corresponding to 83.6324 degrees RA and 22.0174 degrees Dec. The local catalogue places it about 6,300 light-years away. Its referenced angular extent is approximately 7 by 5 arcminutes.
Observing tips
This is rated as a moderate target at magnitude 8.4. It is associated with winter observing, with midnight placement typically strongest around December. From 52 degrees north its theoretical meridian altitude is about 60 degrees; local horizons and the live altitude chart determine the practical window.
A small telescope under reasonably dark skies is a good starting point; use the live altitude chart to choose its highest point.
What to expect
The SIMBAD classification for the matched source is SNR. The SIMBAD record currently connects it to 6567 bibliographic references.
At roughly 7 arcminutes across, it benefits from a narrower field and adequate image scale. Use the listed 7 by 5 arcminute extent to check framing, and treat catalogue magnitude as integrated brightness rather than a direct measure of visual contrast.
