This is 4 hrs of Luminance data, spread over two nights (total of 24 x 600s). Unfortunately I didn't orient the camera exactly the same for one hour the 2nd night (oops!!! At least I noticed then and was able to fix it for the rest of the session) so the edges don't have quite as much detail and depth, though the main portion is all 4 hrs.
