Lunar Eclipse time lapse movie of images from the rooftop sky camera at Ladd Observatory. Each second of video shows 5 minutes of changes in the sky above Brown University in Providence, RI. The entire night is compressed down to less than 2 1/2 minutes.
The brightness of the Moon causes artifacts such as lens flare and CCD blooming, except during the total phase of the eclipse.
The video consists of 3,600 still images taken between dusk and dawn on Sept. 27-28, 2015. Each exposure is 10 seconds long. The field of view is about 140 x 90 degrees with the zenith at center. North is at the right and west is at the bottom. The glow of light pollution from downtown can be seen at the lower left.
The camera uses a red / near infrared filter. It is very sensitive to the amount of moisture in the atmosphere. The filter blocks out some of the light from street lights which allows the Milky Way to be captured on clear nights, despite it not being visible to the human eye.
