Eskimo Nebula. 4-17-15

The Eskimo Nebula, NGC 2392/Caldwell 39, is a planetary nebula. The shape of this nebula resembles a face in a hood. These images were taken with the 14 inch and the MCX. Exposure was 3 seconds and the images were captured just as the nebula was eclipsed by a tree!  The nebula is a greenish/blue and looks almost square in these images. I tried to get some shots without the focal reducer, but I didn't have time before the nebula disappeared behind the tree. The first image is cropped, the second show the nebula in the imaged field with a .5x focal reducer.
