The spiral galaxy NGC 5907 (Knife Edge Galaxy, Splinter Galaxy) in the constellation Draco. The edge-on galaxy NGC 5907 is approximately 40 million light-years from Earth and measures 150,000 light-years in diameter. In 2006, an international team of astronomers announced the presence of an extended tidal stream of stars surrounding the galaxy that might be the relic of a gigantic collision between galaxies or the capture of a small satellite galaxy. NGC 5907 was discovered by the German-British astronomer William Herschel in 1788 (source: Wikipedia).

Forty-six 3-minute exposures (138 minutes total exposure) at ISO 800, taken on June 1, 2019 and on June 26 / 27, 2019, were added for this shot with the DeepSkyStacker software and the final image processing was done 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).
