M57 Ring Nebula.
This is a planetary nebula in the constellation of Lyra. Planetary nebula are so named because, they are small, round and look like planets.
A planetary nebula is a star entering the final phases of it's life cycle. The more massive stars go out in spectacular style as a supernova. The smaller stars, like that of our Sun. Enter their penultimate phase, that of a white dwarf star, with a little less pazzazz. Though they are no less beautiful.
Captured on 10th of February in Newhey, UK.
Boring techie bit.
Skywatcher quattro 8" S & f4 aplanatic coma corrector
HEQ5 pro mount guided with an Altair 50mm & GPcam setup
Canon 450D astro modded with Astronomik CLS CCD EOS APS-C clip filter. Intervalometer used to control the exposures.
15 exposures of 180 seconds at ISO 800 (perhaps over exposed it).
Stacked in DeepSkyStacker with darks, flats, dark flats & bias frames. All processing done with StarTools.
