    I agree with Björn to specify the Bayer letter (or Flamsteed number).
    Because I want to learn most starnames I like if they are specified as well.
    There are some differences in starname assignments if you look at different
    sources. For example: epsilon Cygni is named Gienah according to ref. 1.
    This name is used for gam Corvi according to ref. 2.
    
    ref. 1: Sky Catalog 2000.0 Volume 1 (Cambridge University Press 1982)
    ref. 2: The Photographic Atlas of the Stars  (Institute of Physics
    publishing)
    I love this latter book as the sky is presented in photographs with about
    the same
    limiting magnitude as I experience while using my 7x50 binoculars.
    I use this atlas to improve my knowledge of the constellations.
    Opposite to every photograph is a map of the same part of the sky with the
    brighter stars provided with their Bayer letter or Flamsteed number.
