| This wide region around second magnitude star, Sadr, at the heart of Cygnus the swan, is awash in nebulosity. A huge cloud of hydrogen emission cloud spans over 100 light years at a distance of about 5000 light years. Sadr is a foreground star at a distance of only 750 light years. The brighter emission region in the lower left, divided by a dust lane, has been termed the Butterfly Nebula. To the north of Sadr, which is above the star in this image, is the open cluster NGC 6910. This image combined 60 minutes of red, 40 minutes green and 50 minutes of blue exposures, all unbinned. A QSI-583 camera was used through a Takahashi Sky90 refractor at f4.5. |
