Comet Holmes/17p
This comet exploded from a 17mag comet to about 3mag overnight. At mag 3, it was visible to the naked eye for several months and grew to a size larger than the sun. The change was discovered around October 22. My first images in the backyard were around Nov 5. In this highly processed image, you can clearly make out several jets streaming from the comet. What looks like the core of the comet is merely more dense gases surrounding the core.
This was a single 241 second image using the 764mm f/4.8 Challenger scope and processed using photoshot hipass filtering.
