NGC 4438: The Eyes

These interacting galaxies (NGC 4438 on the left and NGC 4435 to the right) lie in the heart of the Virgo cluster. If either of these galaxies was a spiral, such structures were disturbed long ago by gravitational forces due to close encounters with other galaxies and the heavyweight - M87. These galaxies are around 40 million light years away.

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 = 60 minutes binned 1x1

Red = 10 minutes binned 2x2

Green = 10 minutes binned 2x2

Blue = 10 minutes binned 2x2
