Read full thing again. Got most of that. I guess what I had wrong was that the thing acting like a point source is only a small patch of the star. But why does the small patch twinkle exactly? My visual of it was the "line of photons" gets warped here and there and misses your eye entirely, but you mentioned dark spots etc as the cause.
Also makes me wonder why it wouldn't be a moving patch that you're observing since relatively the star must be moving.
I get the camera obscura better now. Trade off is lower intensity signal, thus longer exposure needed. Thanks!
