Column Explanations:
Name: The Greek letter or Flamsteed number designation of the star, followed by the three-letter constellation abbreviation.
RA and DEC: The star's Right Ascension in hours and minutes, and its Declination in degrees and minutes.
Sep: The separation of the star's components, given in seconds of arc. The larger the separation, the easier it is to see two stars rather than one. Small telescopes in the 60mm range will just be able to split Castor and the two pairs in Epsilon Lyrae on nights when the atmosphere is steady.
Mags: The magnitudes of the stars involved.
Notes: Colors if remarkable, or additional components.
