Early morning photo - mountains lit from the left, photo shot looking south. Checking the map at Himalaya-info.org, looks like you would be looking through the gap between Haramosh (left) and Malubiting (right). The shape looks right, too. http://www.summitpost.org/nanga-parbat/563492/c-150276
Not 100% certain, but I'd say it IS NP.
Fantastic photo in any event - thanks SO MUCH for sharing!
