The Veil Nebula

Click on image for larger version.

These filaments of gas are a portion of a much larger bubble of expanding material generated by the explosion of a massive star. This portion of the complex is often called the "Network Nebula." At an estimated distance of 2600 light years, its large angular extent on the sky indicates that it is an old remnant. By measuring both the size of the bubble and the velocity of the expanding gas, astronomers estimate that this spectacular explosion took place more than 15,000 years ago. A much younger example is the Crab Nebula.

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

Luminance = 50 minutes binned 1x1
 Red = 10 minutes binned 2x2
 Green = 10 minutes binned 2x2
 Blue = 10 minutes binned 2x2
  • The Exposure times above refer to each of the 9 frames that make up this mosaic. This works out to be 12 hours of exposure time invested in this project.
  • Most of the 20in RC data shows details that are equal to or less than 2 arcseconds. (One frame nearly equalled 1")
  • One iteration of L-R deconvolution (sharpening) algorithm using CCDsharp was applied to the luminance images.
