Description

Messier 8 or NGC 6523 is a giant interstellar cloud in the constellation Sagittarius. It is classified as an emission nebula and as an H II region.

In a good sky blasted sideways by a full moon Narrow Band was the only option. So I used M8 for Narrow Band focus preparation while waiting for the the Helix to come up. As luck would have it the seeing was spectacular early on and the shorter 180s exposures really helped to get enough data on what is a pretty bright object anyway. By the time the Helix came up the seeing had dropped off so there you go.  A clear sky did not go to waste.
