Armchair Eclipse Watching

Looks like Tony’s done it again! His video of last month’s lunar eclipse was being passed around on a cell phone at the last astronomy club meeting, so I wrote to Tony and ask him if he’d share it with you, too.

Tony said the video shows the moon going from totality to uneclipsed, and displays 2-1/2 hours in 10 seconds. The movie is made up of 270 individual frames – each shot with his Canon T1i DSLR mounted piggyback on his telescope, while it was tracking at the Quantum Skies Observatory in Pulaski.

Exposures at the beginning of the set are ¼ sec at ISO 1600, and those at the end are 1/4000 sec at ISO 800 (factor of 2000x brighter/dimmer!)  The frames were taken about 30 seconds apart, so while the video comprises 2-1/2 hours of real-time, when run back at 30 frames per second it only lasts ten seconds.

There won’t be any more lunar eclipses visible around Wisconsin in 2014, but next year on September 28th we’ll have another total lunar eclipse visible from all of the continental U.S. We’ll get to see a partial solar eclipse this year on October 23rd, too, although we’re itching to see the total solar eclipse that will fall just 500 miles south of here in 2017. Road Trip!

Thanks again for sharing, Tony!
