Are the stars that we see in constellations within the Milky Way galaxy?

[QUOTE="snorkack, post: 6836852, member: 436348"] There are more options. Omega Centauri is a naked eye object and a lettered part of the constellation. But it is neither a star nor a galaxy. It is perceptibly extended... for telescope. Ptolemy catalogues it as a star (on centaur´s back), it took Halley´s telescope to spot its nebulosity. It actually is a star cluster, in Milky Way. There are other clusters designated with star letters, such as Chi and h Persei (also in Milky Way). And more clusters under star numbers, such as 47 Tucanae (in Milky Way) and 30 Doradus (not in Milky Way). But these do not seem to form parts of constellation figures. Andromeda herself is in northern sky and has a story, but her Nebula notoriously does not... Ptolemy makes no mention of nebula, only mentioned in 10th century Arab sources. And Doradus, Mensa and Tucana are southern sky. How far do the pictures of Goldfish and Toucan rely on the nebulosity of the Clouds, besides the stars in the foreground in Milky Way? [/QUOTE]
