Editing Bayer designation (section)

== Bayer's miscellaneous labels ==

Although Bayer did not use uppercase Latin letters (except ''A'') for "fixed stars", he did use them to label other items shown on his charts, such as neighboring constellations, "temporary stars", miscellaneous astronomical objects, or reference lines like the Tropic of Cancer.<ref name="LostStars">{{cite book

Bayer did not intend such labels as catalog designations, but some have survived to refer to astronomical objects: [[P Cygni]] for example is still used as a designation for Nova Cyg 1600. Tycho's Star ([[SN 1572]]), another "temporary star", appears as B Cassiopeiae. In charts for constellations that did not exhaust the Greek letters, Bayer sometimes used the leftover Greek letters for miscellaneous labels as well.<ref name="LostStars"/>{{rp|p. 131}}
