NGC 255

NGC 255 is a fairly small barred spiral galaxy around 70 million light years away. Many HII regions and blue starforming regions adorn its spiral arms near the nucleus. If you dim the lights in your room, you may be able to see the exceedingly dim outer arms of this galaxy. Also note the assortment of background galaxies (especially the upper left of the image). Less than 1/2 degree away is a more famous object- the planetary nebula NGC 246.

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

Green = 20 minutes binned 2x2

Blue = 20 minutes binned 2x2
