At the top right corner of the frame, Markab itself marks a corner of an asterism known as the Great Square, found within the boundaries of the constellation Pegasus, the flying horse. The wide and deep telescopic view rides along for some 5 degrees or about 10 times the angular diameter of the Full Moon, with blue reflection nebulae scattered around the scene. And even though this line-of-sight looks away from the plane of our Milky Way galaxy, it covers a region known to be filled with nearby molecular clouds. The associated dust clouds, high latitude galactic cirrus, are less than 1,000 light-years distant. Still apparent, but far beyond the Milky Way, are background galaxies, like the prominent edge-on spiral NGC 7497 near picture center.
