Just 4 degrees south of Sirius lies the splendid open star cluster M 41 (NGC 2287). Under good sky conditions you might catch it with your naked eyes as a nebulous patch. And with a pair of binoculars it is resolved into an impressive group of stars (however, using a telescope at higher magnification does not show the cluster well since it is a quite loose concentration of stars). M 41 is believed to have a distance of 2400 lightyears and an age of about 240 million years. Therefore M 41 lies about 280 times far away in the background of our stellar neighbor Sirius.
