κ Bo÷tis


Kappa Bo÷tis is yet another very attractive binary with colour contrast, a yellow primary (some say white) and deep blue companion.
      4.5, 6.6; 235║, 13.4".

Note that kappa2 is the primary. A truly wonderful sight.

Kappa is easily found by starting at the tip of the handle of the Big Dipper (eta UMa). Centre eta UMa in your glasses then move one binocular field northwest: kappa is in the middle of your view, just above the slightly fainter iota Bo÷tis: binoculars.

Iota is an easy binocular double, yellow and blue: 4.8, 7.5, 33║, 38.5".
