I was starting to do the Witches head but the camera would not focus not matter what I did. My thought was where the stars too Faint. so I turned to Orion with it big bright star.
I did get focus but it turned out the program kept asking me to increase the step size . It turned out it was the very opposite I had to make the steps smaller to the perfect curve.

I had planned to do this as a one shot for both which i still will be doing Plus a 50mm shot of the whole area and the Huge Bernard's Loop of the Whole Orion Area.

This is 148 shot 2 min long all night long then the next night I had to take shorter shots 60 sec , 30sec and 15 sec to over come the blown out core of Orion.

The following where my first look at this area with the nikon D810 camera and 420mm lens.
