William Tyler Olcott,
Star Lore Of All Ages — Cygnus…
(1911)
“ Cygnus is a splendid field for telescopes, great and small. Its chief object of beauty is the incomparably beautiful double star, Beta Cygni, also known as " Albireo," situated in the base of the Cross and in the beak of the Swan. Even in a small telescope the contrast in the colours of these two close set stars is well emphasised, and the sight of these suns, the one gold, the other blue, never fails to charm all who view them. ”
