This galaxy shining through the outer layers of the milkyway was exposed more detailed (with longer focal length) and with greater depth (by longer exposures of 900 and 1200 seconds) than before. Because of the smaller field of view only the galaxy could be imaged; the aesthetic pairing with the open cluster NGC 6939 in Cepheus is shown in this wide field image.
