FG Sagittae
(Preview)
The supergiant star FG Sagittae, is the nucleus of the faint planetary nebula PK 60-7°1. On first glance, FG Sge looked rather ordinary. It was recognised as a variable star only recently in 1943, even though it was first photographed in 1894. In 1894 the star was at photographic magnitude +13.6, in 1...
