Can y'all help me understand an apparent oddity? Six months, at least, of adding a new exposure every few nights, right? I can understand why the sunset light is consistent (sun was always 7 degrees below the horizon), spread by the north-south procession through the changing seasons. Venus appears as dots, so I'm guessing the exposures were under a minute each. The building lights, too, look like what I'd expect: a few very bright, as though they were on nearly every evening, and a few dimly lit (on during just a few of the exposures).
Why, though, are those clouds so sharp and dark, as though they maintained their shape and position throughout much or most of the process?
