Best of AOP - Galaxies


M98 is one of the many members of the Virgo Cluster of galaxies around 40-50 million light years away. Generally the expansion of the universe provides a good method for measuring galaxies at this distance- however M98 has a large velocity within the Virgo Cluster and instead of redshifted light the galaxy is one of a few blueshifted examples. This means that we observe the net velocity towards us due to the addition of the its recessional velocity and its intrinsic velocity in the cluster.

The high inclination of the galaxy severely dims many of the star forming regions in the disk. A face-on view might reveal a galaxy similar to M106. Due to the paucity of guide stars for this object- it was not possible to better center the image.

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 = 70 minutes binned 1x1

Red = 20 minutes binned 2x2

Green = 20 minutes binned 2x2

Blue = 20 minutes binned 2x2
