Here is a closer look at the Lagoon Nebula (Messier 8). This image marks another milestone on this cosmic journey; it is my first image using guiding. Guiding allows for longer exposure shots by stabilizing a ‘guide star’ in the field of view. This guide communicates with the mount which adjusts itself continuously to keep the target in the same spot while imaging.
The Lagoon Nebula is an emission nebula in the constellation of Sagittarius. The previous blog post gives a wide field view of the Lagoon Nebula and it’s sidekick the Trifid Nebula (Messier 20).
