Description

The Fireworks Galaxy was discovered by William Herschel in 1798 and is located at the border of the constellations Cepheus and Cygnus. It is about 25 million light-years from earth and the apparent size is 16′.8 × 11′.2.  It is obscured by interstellar matter due to its angular proximity to Milky Way's galactic plane.

Some notes on processing: I conducted a 2xDrizzle (that is why scale is shown at 0.481 arcsec/pixel whereas the native scale of the scope/sensor is at 0.961 arcsec/pixel) to increase resolution and sharpness since I could afford to trade it off against the increase in noise with 18hrs of integration. The drizzle benefitted from frequent dithering and a lot of data to play with (542 subs).

CS, John
