Best of AOP - Galaxies

NGC 3169 and NGC 3166

Located in Sextans (practically a self-referential constellation since you basically need a Sextant to find the stars...) NGC 3169 (to the upper right) and NGC 3166 (in the lower left) make a very pretty pair of galaxies. They are truly near to one another and affect each other's structure. Most notably it appears that NGC 3166 has quieted down in terms of star formation; while NGC 3169 continues to produce new stars as indicated by the bluish spiral arms and pink star forming regions. NGC 3169 and 3166 are separated by a mere 50,000 light years (half the diameter of our own galaxy). These galaxies dance some 60 million light years in the distance.

LRGB color production was used to create this image.

Two iterations of L-R deconvolution (sharpening) algorithm using CCDsharp were 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 = 90 minutes binned 1x1

Red = 20 minutes binned 2x2

Green = 20 minutes binned 2x2

Blue = 20 minutes binned 2x2
