Open Clusters NGC2168 (M35) with NGC2158



Object Data
Description M35 is a large and bright open cluster that is best when viewed at low magnification power. Under dark skies it is just visible to the naked eye, and it is an excellent object for binoculars. Just 30 arcminutes southwest of M35 is the dim (8.6 magnitude) and much more distant (4.9 kpc) open cluster NGC2158.
