A long exposure image of the first half of the Sept. 27 lunar eclipse, taken from near Boston’s Zakim Bridge, showing the moon’s decreasing luminosity and characteristic red hue at totality resulting from the wavelength-dependent Rayleigh scattering of the earth’s atmosphere. The image was taken by stacking 320 images taken at 30-second intervals.

Exposure Time: 2 sec. x 320
