Description

For this image, I have chosen a field of view that includes not only the Lobster Claw Nebula but also the nearby open star cluster NGC 7510. It's interesting to see that, with a long enough integration and exposure time, both the H-alpha and OIII components seem to surround the star cluster.

A look at the full resolution is definitely worth it - there are plenty of hidden details and beautiful structures in the nebular extensions.
