NGC 5054

This colorful, somewhat irregular Herschel 400 spiral in Virgo is visible as a faint glow in a 6" telescope, according to Luginbuhl and Skiff. It appears elongated with a mottled core in a 16/18" scope at 150x, according to Kepple and Sanner. At magnitude 10.9v, this galaxy shows a lot of detail and color in this moderate exposure, made using separate luminance, red, green and blue frames. Dust lanes are evident, especially to the southwest of the core, and bluish star forming regions in the two major spiral arms are quite striking. The irregular morphology of the galaxy hints at a possible interaction sometime in the past. A redshift of .058 gives a Hubble distance for this galaxy of 82 million light years, assuming no peculiar motion and using a value of 75 k/s/Mpc for the Hubble constant.

The faint spiral to the northeast (bottom-right), which appears almost edge-on, is magnitude 16 MCG-3-34-40. (Caption by Robert Kuberek)

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 = 90 minutes binned 1x1

Red = 20 minutes binned 2x2
