5. The Night Sky Friday, July 15 · After the just-past-full Moon rises into good view late this evening, use binoculars to look a little above it for Beta Capricorni and, higher, the wide double star Alpha Capricorni. With good distance vision you can normally split Alpha Cap naked-eye. Can you still do this with the bright Moon so close? Saturday, July 16 · With summer almost a third of the way through, the Big Dipper is descending in the northwest after dark and starting to scoop to the right, dipper-wise, as if picking up water to dump over the world in the evening next spring. See the picture below. Sunday, July 17 · Titan, the brightest satellite of Saturn, can be found in a telescope about four ring-lengths east of Saturn this evening and tomorrow evening. With a 6-inch scope you can make out the orange tint of Titan's hydrocarbon- smogged atmosphere.

6. The Night Sky Monday, July 18 · Arcturus is the bright star shining high in the southwest these evenings, far above Saturn and Spica. Arcturus is a yellow-orange giant 37 light-years away and about 150 times as luminous as the Sun. Its pale ginger-ale color is plain to the unaided eye. Compare this to the icy blue-white of Vega overhead, equally bright. Look far to the right of Arcturus, at roughly the same height, for the Big Dipper, oriented about as shown here.
