There are actually two lists, one for deep-sky objects, and this one for double and variable stars. All objects are listed in Right Ascension order so that you can view them as they rise in the East and set in the West. Information provided on double and variable stars includes: Object, Right Ascension, Declination, Magnitude, and Separation of the components.

A finder chart can be printed here:  http://www.aavso.org/sites/default/files/finder_charts/PER.GIF

Use any convenient star chart or planetarium program to determine the magnitudes of neighboring stars, or use:

  • α Persei 1.8 (alpha Persei)
  • ζ Persei 2.8 (zeta Persei)
  • ο Persei 3.8 (omicron Persei)
