This is a two panel shot of the area the middle being the Horse Head. The right side took three night the left side took two night. the difference was the tree next to the mount got pruned so the shots went to 4 am.

This was my first trial of using the rotation marks and getting the cameras square to the shot all 5 night had the very same error 3.3 degrees within the 5 degree limit I had set. I watched each night to see if I had to change rotation. The two shots fitted together perfectly making this method very workable.

This was the fav nebula of mine since I was a kid seeing the close up of the Horse on the red background. My only regret my father did not get to see this shot.
