Best of AOP - Galaxies

Hercules Galaxy Cluster

Each "fuzzy thing" is another galaxy entirely. In this image you can count 20-30 of them. The cluster of galaxies extends well beyond this field of view. They are estimated to be on the order of 300+ million light years away. Several of the galaxies in this image are interacting as is often the case in clusters of galaxies. The most prominent example is NGC 6050 (middle) in which two spiral galaxies have interlocked.

LRGB color production was used to create this image.

If done again, this image would need longer exposures in both luminance and color components.

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 = 105 minutes binned 1x1

Red = 15 minutes binned 2x2

Green = 15 minutes binned 2x2

Blue = 15 minutes binned 2x2
