Lobster Claw Nebula

The Lobster Claw nebula, also known as SH2-157 is a bright nebula found in Cassiopeia.
Sky was quite clear at start but turned cloudy when I was 2 hours in, so the signal to noise ratio was pretty low later on. However, the final image has exceeded my expectations already. I shall revisit this target in the future.
