| M48, An open cluster - this image cropped and reduced from the original photo |
| M48 is a quite conspicuous object and should be a naked-eye object under good conditions. The smallest binocular, or telescopes, show a large group of about 50 stars brighter than mag 13, the total number being at least 80. The more concentrated core extends over about 30 arc minutes, while the outskirts reach out to about 54', corresponding to a linear diameter of 23 light years at its distance of 1,500 light years. The age of M48 was estimated to amount about 300 million years. It can be found on the other side of the Milky Way from Orion, about the same height as M42. |
