About Ghost of Jupiter

Ghost of Jupiter (C59) is catalogued as a planetary nebula in Hydra. Its J2000 position is RA 10:24:46, Dec -18:38:33, corresponding to 156.1922 degrees RA and -18.6423 degrees Dec. The local catalogue places it about 3,568 light-years away. Its referenced angular extent is approximately 0.1 by 0.51 arcminutes.

Observing tips

StarWatchr rates this as a hard target at magnitude 7.7. It is associated with spring observing, with midnight placement typically strongest around February. From 52 degrees north its theoretical meridian altitude is about 19.4 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 4.7 km/s. The SIMBAD record currently connects it to 842 bibliographic references.

At roughly 0.1 arcminutes across, it benefits from a narrower field and adequate image scale. Use the listed 0.1 by 0.51 arcminute extent to check framing, and treat catalogue magnitude as integrated brightness rather than a direct measure of visual contrast.
