Wow!,certainly very impressive image-and interesting 'in the field' approach.
Barry- I am just wondering if you could let us know how you did the other parts of the image-exp time for night sky,I am wondering if you had a small EQ mount you take into the field for your camera.I take it its a composite image.Hope you do not mind revealing some more details (the bellies are revealed

so I guess you will not mind sharing a few how too's of this lovely image).
Cheers Chris
