Best of AOP - Galaxies


This face-on spiral galaxy is often called the Southern Pinwheel. It has two major arms (and a third fainter one) which present the countenance of this barred spiral. This galaxy is the birthplace of massive stars. In the past 80 years there have been 4 observations of these large stars blowing up (supernovae). This is 10 times the expected rate of such events- and to this day a topic of current research and uncertainty.

LRGB color production was used to create this image.

Poor seeing "attacked" in the middle of the acquisition of this data set. Due to its low altitude in the sky- this has a

dramatic effect on the outcome of the image.

Three 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
