Binocular double

What does every good astronomer do when waking up at 1:00 in the morning for no apparent reason? Why, sit out under the stars, if the sky is clear, and do some astronomy. That's what I did the other night. At that time of night form my patio, the head of Draco was in good position for observing, so I pointed the Nikon 10x70 binocular toward Nu Draconis (the star Kuma) and was treated to a fine binocular double. Though not colorful, Kuma is one of my favorite doubles in an astronomy binocular for its closely matched magnitudes and just enough separation to make it fun in a binocular. It's been described as a pair of eyes and I agree. Next time you are up at 1:00 in the morning, grab a binocular and take a look.
