Panoramic Eclipse Composite with Star Trails
Explanation: What was happening in the sky during last week's total solar eclipse? This featured
little-planet,
all-sky, double time-lapse, digitally-fused composite captured celestial action during both night and day from a single location. In this 360x180
panorama, north and south are at the image bottom and top, while east and west are at the left and right edges, respectively. During four hours the night before the eclipse,
star trails were captured circling the
north celestial pole (bottom) as the
Earth spun. During the day of the total eclipse, the
Sun was captured every fifteen minutes from sunrise to sunset (top), sometimes in partial eclipse. All of these images were then digitally merged onto a single image taken exactly during the
total solar eclipse. Then, the Sun's bright
corona could be seen flaring around the dark
new Moon (upper left), while
Venus simultaneously became easily visible (top). The tree in the middle, below the camera, is a
Douglas fir. The images were taken with care and
planning at
Magone Lake in
Oregon,
USA.
