NGC 6992: 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.

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")
The spectacular background image was graciously offered by
Mike Cook. Please
to see his original image.
When zoomed out, it is difficult to see how the hi-resolution
image overlaps (overlays) the background image. However, once the
larger images are viewed this becomes obvious. I chose not
to try and blend the two images as they are sufficiently different that
the combination would be a detriment to both.
One iteration of L-R deconvolution (sharpening) algorithm using
CCDsharp was applied to the luminance images.
