At long last, the skygrid is done. A year ago, I started the process to capture an image of the zenith sky every two minutes from 4 in the morning until 9 at night. Today the Sun crossed back into the sky of the Northern Hemisphere, and the camera on my porch took the last set of photos of the zenith. Here is the color spread of the equinoctal day:
And here is the final yearly grid, 495 x 365, or 180,675 separate squares (click to embiggen):
I will be processing another time-lapse movie of the Winter Half of the skygrid when I have time. Until then, check out the Summer Half.
