M8 - Lagoon Nebula

M8 - The Lagoon Nebula (NGC 6523) is a giant interstellar cloud in the constellation Sagittarius. It is between 4,000-6,000 light-years from the Earth and is 110 ly across by 50 light years wide. Although this is a Messier object it does not change my current status as I have already imaged this two years ago.  However, it was only 5 minutes total exposure taken when I was just learning.  In that image you really could not see the outline. This is far from perfect but it is a huge improvement over the image from 2015.
