NGC 210

Click on image for larger version.

NGC 210 is a rather strange galaxy due to its structure. The inner portion is very bright and the two dust lanes (just perceptible here) give way to spiral structure. Yet the out two filamentary arms are almost disconnected, making the galaxy better described as a barred spiral. These ring-like galaxies have been studied by astronomers to better understand how various shapes of galaxies evolve. Also notice the small background galaxy on the right side of the NGC 210. Its light is reddened (blue light is scattered) as it passes through the disk of NGC 210.

Equipment

Meade 16in LX200 telescope operating at f/6.3
SBIG ST8E CCD camera with color filter wheel

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

Luminance = 45 minutes binned 1x1
 Red = 20 minutes binned 3x3
 Green = 20 minutes binned 3x3
 Blue = 40 minutes binned 3x3
  • One iteration of L-R deconvolution (sharpening) algorithm using CCDsharp was applied to the luminance image.

  • Digital Developement (DDP) via Maxim/DL was also used in order to display the the very dim and very bright details of the image simultaneously. The mid-level value was raised so that only the nucleus of the galaxy was affected. Further manipulation might have brought out the dust lanes more- but probably at the expense of a noisier image.
