About Eskimo Nebula
Eskimo Nebula (C39) is catalogued as a planetary nebula in Gemini. Its J2000 position is RA 07:29:10, Dec +20:54:42, corresponding to 112.2949 degrees RA and 20.9118 degrees Dec. The local catalogue places it about 4,100 light-years away. Its referenced angular extent is approximately 0.34 by 0.34 arcminutes.
Observing tips
This is rated as a very hard target at magnitude 9.2. It is associated with winter observing, with midnight placement typically strongest around January. From 52 degrees north its theoretical meridian altitude is about 58.9 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 PN. A published radial velocity value is 84.2 km/s. The SIMBAD record currently connects it to 746 bibliographic references.
At roughly 0.3 arcminutes across, it benefits from a narrower field and adequate image scale. Use the listed 0.34 by 0.34 arcminute extent to check framing, and treat catalogue magnitude as integrated brightness rather than a direct measure of visual contrast.
