Best of AOP - Galaxies


M90 is one of the few large spiral galaxies in the Virgo Cluster. This galaxy seems similar to M64 in that the outer arms are very smooth and devoid of star formation. In fact, there are few bright pink HII regions which might indicate any star birth in this galaxy. At a distance of 60 million light years away it is not alone and apparently disturbing its neighbor IC 3583. Astronomers have measured the velocity of this galaxy and have found that it is actually moving towards us! M90 has enough velocity to escape from the gravitational bonds of the Virgo Cluster of galaxies.

LRGB color production was used to create this image.

Excessive winds deteriorated the resolution due to wind-shake.

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 = 105 minutes binned 1x1

Red = 20 minutes binned 2x2

Green = 20 minutes binned 2x2

Blue = 20 minutes binned 2x2
