Cancer is the most inconspicuous Zodiac constellation, but is rather easy to find. It resides directly between Castor/Pollux and Regulus. With no stars brighter than +3.5 Mag, it's best viewed from a dark location.
Cancer contains two showcase objects: The Beehive Cluster (M44) and iota Cancri, a double star that rivals Albireo in beauty. Thru a small scope at medium power you will see a bright yellow star with a smaller powder-blue companion. Worth searching for!
