NGC 428

Click on image for larger version.


 NGC 428 is approximately 70 million light years away. Its distorted shape leads astronomers to think that this galaxy may have absorbed another galaxy in its recent history. The many starforming regions and bright blue star clusters hint at the activity present in the disk of this galaxy. The "blob" beneathe the galaxy is actually a very colorful triple star system (see the image of it displayed for that purpose to the left).

20in RC Optical Systems telescope Operating at f/8.4
Paramount ME Robotic Telescope Mount
SBIG ST10XME CCD camera with color filter wheel

L R G B color production was used to create this image.

Luminance = 90 minutes binned 1x1
 Red = 20 minutes binned 2x2
 Green = 20 minutes binned 2x2
 Blue = 20 minutes binned 2x2
  • The triple star was a very nice surprise.
  • 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 the very dim and very bright details of the image simultaneously.
