Description

Next one from the Sharpless catalogue of faint nebulae.

It's not a common object, and of course... it's faint.

Sh2-170 is an emission nebula in Cassiopeia at around 7500 light years away.

Always taken pictures of the past, something that happened 7500 year a go and now arrive to the earth.

The bright star at the centre of the nebula is ionising the surrounding hydrogen gas, causing the nebula to glow.

This nebula is about 2/3 the diameter of the full moon.
