Kaboom! IC 443 Super Nova Remnant
Bob Townsend
Shown here is the IC 443 super nova remnant. It's a composite of 30 Ea hydrogen alpha (Ha) 10 minute subs pasted onto 30 Ea 10 minute RGBs. Including the Ha data improves the red contrast and detail that were otherwise a little washed out. The sun doesn't have enough mass to go out this way in 3 to 4 billion years. Current theory says that you need 1.4 to 1.9 solar masses. The sun will become a red giant with a size out to the orbit of mars and start puffing off small rings of mass resulting in a planetary nebula.
The image was taken at my observatory in Placerville, California, on the nights of 5-6 November 2007 with my E200 800 mm focus F4 Takashi astrograph and spectrum modified Canon 350D DSLR.

Be sure to include your first and last name and the name(s) of any people in your submission. To the best of your ability, provide both the common name and the genus and species of any plants or animals. Common names are lower case, as in the live oak tree.
