Best of AOP - Galaxies

NGC 4449

This irregular dwarf galaxy is part of the Canes Venaticorum group of galaxies some 12 million light years away. This galaxy is very similar to our own LMC (Large Magellanic Cloud) in both structure and size. The central part of the galaxy consists of a population of very young stars which extend through the galaxy in a bar formation. Astronomers estimate that these stars are not much older than 5 million years in age. The numerous red regions are the HII regions that are currently forming stars. Massive dark clouds of gas and dust (dark blobs in picture) await future episodes of star formation. Chains of blue outline the baby-boom of stars in this galaxy.

LRGB color production was used to create this image.

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 = 75 minutes binned 1x1

Red = 15 minutes binned 2x2

Green = 15 minutes binned 2x2

Blue = 15 minutes binned 2x2
