One of my biggest project with over 10h of exposure time.
This is a region with several objects located right between the constellations Cassiopeia and Cepheus.
The most known objects in this Image are the Lobster Claw Nebula, the Bubble Nebula and the Northern Lagoon Nebula. Look at the 2nd image for better understanding.
