William Tyler Olcott,
A Field Book of the Stars — Cepheus
(1911)
“ CEPHEUS (sē'-fūs) (Face North.) Location.—A line drawn from (α) to (β) Cassiopeiæ and prolonged about 18 degrees strikes (α) Cephi. The nearest bright star west of Polaris is (γ) Cephi. Cepheus is an inconspicuous constellation, lying partly in the Milky Way. A view of this constellation through binoculars will repay the observer. Cepheus is characterized by a rude square, one side of which is the base of an isosceles triangle. Look for the so-called garnet star (μ) , probably the reddest star visible to the naked eye in the United States. The star (ζ) has a blue companion star. ”
