   cluster that lies in Capricornus the Sea
   Goat. It orbits our galaxy within a halo
   region some 27,000 light-years away.
   The bright star to its left is magnitude
   5.2 SAO 190559. (3.6-inch Astro-

7. CHASING A WATERFALL
   You’ll find the asterism observers call
   Kemble’s Cascade in one of the sky’s
   faintest constellations, Camelopardalis.

   dozen stars in this string stretch 2.5°
   and range from 5th to 9th magnitude.
