| Notes: | Shot this object, and NGC 6950, based on The Sky & Telescope Deep Sky Wonders column by Sue French ("Arion's Dolphin", October 2008, pages 71-73). They were well away from the nearly full moon rising in the East, and could be imaged in one night (each). Poskus 1 (a little below center of this image) is in the Deep Sky Hunters Database, and has been referred to as a lute, a mandolin, or a flyswatter. Gamma Delphini is the bright (double) star at the lower edge |
