Background

IC 2602 is the “Southern Pleiades” — one of the closest open clusters to Earth at only  480 light-years, and one of the brightest naked-eye clusters in the southern sky. Around 50 million years old, it contains about 60 confirmed members spread over more than a degree, dominated by the bright blue star θ Carinae.

My Observing Notes

30-cm (SkyWatcher 12-inch f/5): Naked-eye and unmistakable. Used throughout the night as a star-hopping reference to other Carina deep-sky objects (NGC 3199, IC 2714 / Mel 104, Mel 101, NGC 3766, NGC 5286). Far too large for the eyepiece — best appreciated with binoculars or the finderscope.(10 April 2026)
