About this image and M57:
M57, also known as the Ring Nebula, is a planetary nebula that was formed approximately 1,600 years ago, give or take 200 years or so. The nebula has been formed by a star shedding it's outer layers into space as the star itself becomes a white dwarf.
Currently the ring nebula is very bright, the below images being single monochrome subs of just 10 seconds in length. But as the centuries pass by, the ring of gases will expand and become dimmer and dimmer until eventually it becomes indistinguishable from the background of space. The universes version of blowing smoke rings :o)
Currently the ring nebula is very bright, the below images being single monochrome subs of just There is also a very faint shell of ionised hydrogen gas surrounding the main ring of the nebula which I did not capture this time but using a Ha filter I should be able to capture this and then add it to the image later on.
