Best of AOP - Galaxies

NGC 6946

Sometimes known as the Fireworks Galaxy, NGC 6946 is both a spectacular and dim galaxy in Cepheus. At a distance of 10 million light years, this galaxy is one of about a dozen nearby neighbors to the Milky Way. Like M83, this galaxy has had an enormous number of supernovae explosions in the past 60 years. If we could watch this galaxy with years passing as seconds- every moment or two we would see a star blow up!

LRGB color production was used to create this image.

The image averaged less than 1.8" with a majority of the data being at 1.4" for 900 second exposures.

One iteration of L-R deconvolution (sharpening) algorithm using CCDsharp was applied to the luminance image.

Digital Development (DDP) via Maxim/DL was also used in order to display the very dim and very bright details of

the image simultaneously.

Luminance = 125 minutes binned 1x1

Red = 20 minutes binned 2x2

Green = 20 minutes binned 2x2

Blue = 30 minutes binned 2x2
