A Lunar Eclipse |
(Home) |
On the night of August 27 / 28, 2007 a total lunar eclipse occurred right across the whole sky all night long. A perfect opportunity to capture the 5 1/2 hour event and compress it into a movie. Many lunar eclipses are not visible from start to end, and / or are at times of the year where the weather is uncooperative.
This "shot" was taken at Mistletoe Observatory in Monmouth Oregon using the FSQ 106 and Astro-Physics 900. Even with a hydrogen alpha filter, the scope had to be stopped down with a piece of cardboard. The movie is a sequence of 0.1 second images. It is unbinned ST8E data.
The real fun of this shot was that the event was managed by a script that I created ahead of time that moved the scope all night (the moon moves a long ways against the sky during this amount of time) and automatically collected the data while I slept. Then the processing was also scripted. With 227 images, there was just too much data to handle manually.
