IC 2581 is a Open Cluster in the Carina constellation. IC 2581 is situated south of the celestial equator and, as such, it is more easily visible from the southern hemisphere. Given its visual magnitude of 4.3, IC 2581 is barely visible to the naked eye, easily visible with the help of a …

Across much of the world, the open star cluster IC 2581 (mag 4.0) in Carina will be well placed in the evening sky in coming weeks. On 27 February it will reach its highest point in the sky at around midnight local time, and on subsequent evenings it …
