Description

Easily the faintest thing I've photographed.
SH2-170 or the small rosette nebula. A supernova remnant.
It lies in the Perseus arm of our galaxy around 7500 light years distant. At its centre is a small, young star cluster, Stock 18. The bright star at the centre of the nebula is ionizing the surrounding hydrogen gas and causing the nebula to glow. To give a sense of scale, the nebula is about 2/3 the diameter of the full moon.
