Description
A star, much like our own, about 851 light years away, went through its death throws. It swelled up to make a Red Giant, then ran out of puff and collapsed. The collapse makes a small white dwarf star and a huge cloud of smoking debris that is made to glow by the small White dwarf inside.
The white dwarf is about the size of the earth, with a mass equal or greater than our sun. The cloud is several light years across now and glows because of the ionizing radiation from the little sun.
Green is oxygen, red is hydrogen and nitrogen.
Our sun will do this in about 5 billion years so go out and get milk, bread and chip board to cover your windows. Tell your boss he is a jerk and take that vacation you wanted.
Taken with a webcam, 30x30second exposures layered with 30x30 second exposures shot through a oxygen narrow band filter. A 80 mm telescope completes the gear.
Picture taken from my back yard deck.

It is always a treat when you post a gallery image. Not just for the amazing quality you get with you intricate processing, but for the stories that go with it. Marking my calendar now so that I know when I can tell off my boss! 8^]

That is impressive to see! Thanks - since there are so few who can do this type of work you should automatically get extra marks! +++

Incredible to see your achievement with relatively simple means! Terrific work, white dwarfs are a bit less violent than novae and supernovae but it's incomprehensible to imagine the compression of matter here in such a star!

Wow! Awesome work! I didn't know a web cam was sensitive enough for nebulae. Cool info, too... I'm running out for chips and soda now!
