About Saturn Nebula
Saturn Nebula (C55) is catalogued as a planetary nebula in Aquarius. Its J2000 position is RA 21:04:11, Dec -11:21:48, corresponding to 316.0451 degrees RA and -11.3635 degrees Dec. The local catalogue places it about 1,400 light-years away. Its referenced angular extent is approximately 0.71 by 0.52 arcminutes.
Observing tips
This is rated as a hard target at magnitude 8. It is associated with summer observing, with midnight placement typically strongest around August. From 52 degrees north its theoretical meridian altitude is about 26.6 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 PN. A published radial velocity value is -46.6 km/s. The SIMBAD record currently connects it to 1024 bibliographic references.
At roughly 0.7 arcminutes across, it benefits from a narrower field and adequate image scale. Use the listed 0.71 by 0.52 arcminute extent to check framing, and treat catalogue magnitude as integrated brightness rather than a direct measure of visual contrast.
