NGC 6960 Cyg 20h46m / +3043' 70' x 6' (<7mag)

The supernova remnant NGC 6960 (Veil nebula, Cirrus nebula) in the constellation Cygnus on August 12 / 13, 2015. Discovered by the German-born British astronomer William Herschel in 1784, this cloud of heated and ionized gas is the result of a supernova which exploded some 5000-8000 years ago. The nebula is 1470 light-years from earth. The brightest star in the image is 52 Cygni. It is a foreground star (206 ± 8 light-years from earth) which can be seen by the naked eye (source: Wikipedia).

Twenty-two 3 minute exposures at ISO 800 with no dark frame subtraction were stacked with Deep Sky Stacker (resulting in a 1 h 16 min exposure) and further processed in Photoshop.
Equipment: Canon EOS 450D Baader modified camera, TeleVue Paracorr Type II coma corrector, 16" f/4.5 "Ninja" dobsonian telescope riding on a dual-axis Tom Osypowski equatorial platform, Lacerta MGEN autoguider, Lacerta off axis system (field of view comparison: image of the moon with the same equipment).
