Closeup of up 2 stars. Alcor, on the left, is smaller and yellowish, Mizar, on the right, is bigger and blue-white.

Look up to see Mizar and Alcor! 🌌🔭 #Mizar and #Alcor make up one of the most famous #doublestars in the sky. These 2 stars are bound to one another by gravity. They’re located in the famous #BigDipper in the northeast on March evenings. It’s lots of fun to see them!

You're a frighteningly talented astronomer for an attorney, Kid... Your work is as excellent as any I've seen. #doublestars

Double stars observation last night, with some tight ones in Draco, and a beautiful Alpha Herculis looking like copper sparkles. Awesome optics of this TS102 f11 ED !

An experiment - it was so gusty last night that I decided to tackle #DoubleStars . A combination of stacks on the easy ones #IotaCancri and #24Com plus video stacking with the tighter pair of #Algieba - Needs more background stars when the weather is less windy! #EAA #astrophotography

Best Double Stars in the Pleiades Cluster Like a gift that keeps on giving, the Pleiades is also home to several fine double and triple stars for small telescopes. Plus, details of a rare comet occultation on Feb. 5.
