| Notes: | This is one of those "where is it clusters"! Dolidze 1 is centered in this image, see just under the centered bright star in the upper middle, and to the East (left), and even with the bright star at the West (right). Description from "Star Clusters", by Brent Archinal and Steven Hynes is "Archinal: Id? Mostly E-W scattering of brighter stars in rich Milky Way field". The "n" in the classification is for faint tendrils of nebulosity that pervades the entire central Cygnus area, some of which can be seen in this rather short exposure |
