ABSTRACT

One of the leading stars in the constellation – Alpheratz or α Andromedæ – is actually a member of the Square of Pegasus, and was formerly known, more logically, as δ Pegasi. A Zodiacal constellation, and of course one of Ptolemy Euergetes’s Originals’. Oddly enough there are no well-defined legends attached to it, though it has been associated with Ganymede, cup-bearer of the Olympian gods. Arcturus is the brightest star in the northern hemisphere of the sky. Canopus is a highly luminous star, but estimates of its power and distance vary considerably. Cygnus is one of the richest constellations in the sky; it is often nicknamed the Northern Cross – certainly it is much more nearly cruciform than is Crux. The only star above the fourth magnitude is a, but Dorado contains part of the large magellanic cloud, in which is the magnificent Tarantula looped nebula round 30 Doradus.
