The naked-eye Beehive Cluster in Cancer, M44 (RA 8h 40.4m, dec. +19° 40’; pictured) is a brilliant binocular object. Covering 1º of sky, its brightest members consist of around a dozen 6th- to 8th-magnitude stars, including three arranged in an obvious isosceles triangle just southeast of centre. The 6th-magnitude stars 39 and 40 Cancri make an attractive pair, while a small telescope reveals over 100 stars.
Cancer has another deep-sky object of note, star cluster M67 (RA 8h 51.3m, dec. +11° 48’). Located 8° south-southeast of M44, this open cluster is 25 arcminutes across, with its brightest members arranged in loose groups interspersed with arcs. It contains around 100 stars from 9th to 14th magnitude.
