I love your contemplation, Jack!
Armando: deep sky with a normal camera at 300mm and such a result? I guess you must have compensated for the earth's rotation somehow? Did you use an orion tripod head or something? Amazing result.
Which camera did you use? Nikon 1?
My father shoots stuff like this at 3000mm with a video camera in black and white using rotating color filters. I sent him your pic to make him think about using a real camera like a D810a
