What You Should See:
With a diameter of nearly 4°, Cr65 is an ideal object for 50mm binoculars, which reveal over 50 stars in this sparse cluster. You will see many chains and groups of stars, with a lovely equilateral triple near the south and the orange CE Tau, a semi-regular variable (mag 4.2 to 4.5) similar to Betelgeuse, to the north.
