NGC 891: Edge-on Spiral in Andromeda

Click on image for larger version.

This galaxy is perhaps the most beautiful example of a near-by spiral galaxy viewed edgewise. Note the small companion galaxies above and beneath the disk. This particular galaxy is of interest to astronomers that study the dynamics of material in the galactic plane of spiral galaxies. In this example, there are sprays of material (gas and dust) that are being accelerated perpendicular to the disk. This effect is not well-understood.

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

Luminance = 120 minutes binned 1x1
Red = 20 minutes binned 2x2
Green = 10 minutes binned 2x2
Blue = 20 minutes binned 2x2

  • There was a problem with the green data set. Only one of the frames was used for the color information.
  • One iteration of L-R deconvolution (sharpening) algorithm using CCDsharp was applied to the luminance image.

  • The AO unit was used for this image.
