M41 (NGC2287) is an open cluster easily located 4 degrees south of Sirius, one of the brightest stars in heavens. You'll enjoy the impressive contrast of Sirius's dazzle light and the modest group of faint stars, M41.
The cluster is positioned at about the west edge of winter's Milky Way, so you'll be fascinated with uncountable stars surrounding this object.
