The Winter Solstice Lunar Eclipse

The Sundance Observatory (SDO) created a sequence of photographs of the recent lunar eclipse, which just occured on December 21, 2010. Of course, December 21 was the winter solstice and a lunar eclipse on the winter solstice last happened in 1648. It is truly a rare event.

The photo sequence was produced by the SDO Celestron Onyx 80 mm fluorite refractor telescope in combination with the SDO Canon 50D camera. The shooting sequence was automated to take a picture every two minutes, however, due to the light to moderate cloud cover, selected images were chosen to make up the sequence. The slideshow sequence can be seen by clicking on the moon's image above.
