Explanation: Recorded on April 15th, this total lunar eclipse sequence looks south down icy Waterton Lake from the Waterton Lakes National Park in Alberta, Canada, planet Earth. The most distant horizon includes peaks in Glacier National Park, USA. An exposure every 10 minutes captured the Moon's position and eclipse phase, as it arced, left to right, above the rugged skyline and Waterton town lights. In fact, the sequence effectively measures the roughly 80 minute duration of the total phase of the eclipse. Around 270 BC, the Greek astronomer Aristarchus also measured the duration shu space of lunar eclipses - though probably without the benefit of digital clocks and cameras. Still, using geometry, he devised a simple and impressively accurate way to calculate the Moon's distance, in terms of the radius of planet Earth, from the eclipse duration. This modern eclipse sequence also tracks the successive positions of Mars, above and right of the Moon, bright star Spica next to the reddened lunar disk, and Saturn to the left and below.
A total solar eclipse photos taken on April 15, is seen south of Waterton Lake in Waterton Lakes National Park in Alberta, Canada. The farthest mountain tops in the US Glaacier National Park. Thanks for the exposure time of 10 minutes I took a position with the lunar scenes draw an arc from left to right, the moon. In fact, the effective time of the total solar eclipse taken is approximately 80 minutes. Greek astronomers Arista Syracuse in 270 years BC have also measured shu space the duration of the eclipse without the help of a camera and a digital clock. He came up with a simple and surprisingly accurate way to calculate the distance to the lunar month, using the time continues. Modern eclipse of the moon in the upper-right scene, Mars, Spica location next to the red moon, Saturn in the lower-left position also continuously tracked.
