Fireworks Galaxy – NGC 6946

Fireworks Final

NGC6946

Discovered in 1789 by William Herschel the Fireworks Galaxy in the Constellation Cygnus is relatively nearby at about 22.5 million light-years from earth. Over the years a number of supernovae have been observed in this galaxy. This photo is a combination of four ten minute photos taken with four different filters (luminosity, red, green, and blue). It was taken through the Celestron Edge HD 11 inch SCT telescope at F7. The camera was the QSI 583wsg.

This is also first light for a new mount, the Astro-Physics 1100GTO with absolute encoders. This mount makes it possible to produce photos with 10+ minute exposures versus 2 or 3 minute exposures with the previous mount.
