Draco is a northern, circumpolar constellation. The constellation almost circumvents Ursa Minor. In greek mythology there are a few dragons associated with the constellation, but one of the stories also features the near by constellation of Hercules. Although Draco passes zenith it does not do so at convenient times during dark times. However, since it is so high in the sky in Sweden it is most convenient do look at it during autumn and early winter evenings. There are no bright objects in Draco but several of the brighter stars are binary or multiple systems. Draco also holds the north ecliptic pole i.e. the point around which Earth's spin axis precess with a period of about 26000 years. The image is a combination of two images.
