This frames the small constellations of Sagitta the Arrow (at bottom) and Vulpecula the Fox (at top), to include a number of deep-sky objects in a wide field of view similar to that of binoculars. At upper right is the asterism the Coathanger, aka Collinder 399 or Brocchi's Cluster. It is immersed in some faint blue reflection nebulosity, notably Van denBurgh 126 to the north. Below the Coathanger is the small round pinkish patch of Sharpless 2-82. Off the left end of the Coathanger is the small star cluster NGC 6802. At lower left is the green planetary nebula Messier 27, aka the Dumbbell. Left of centre is the diffuse patch of red emission nebulosity NGC 6823, and above it the smaller Sharpless 2-88. At bottom, below the two yellow stars in Sagitta, is the globular cluster Messier 71. The field is also laced with lots of distinct dark nebulas, though none carry any Barnard catalogue designations; all are LDN objects from the Lynds catalogue. The field is 15° by 10° , so wider than most binoculars. This is a stack of 14 x 2-minute exposures with the Canon RF135mm lens at on the Canon Ra at ISO 800. No filter was used. The camera was on the MSM Nomad tracker, and the images were the best 14 taken out of a series shot to test the tracking of the Nomad. And taken in early June when the sky isn't astronomically dark. North is to the upper left in this framing.
