Explanation: No special filters - or even a telescope - are required to enjoy a leisurely lunar eclipse (http://antwrp.gsfc.nasa.gov/apod/ap070901.html). In fact, watched from all over the night side (http://antwrp.gsfc.nasa.gov/apod/ap070302.html) of planet Earth, these regular celestial (http://www.mreclipse.com/Special/LEprimer.html) performances have entertained many casual skygazers. Still, this eye-catching picture (http://www.photomeeting.de/astromeeting/_index.htm) of a lunar eclipse may look unfamiliar. To make it, astroimager Stefan Seip set his camera on a tripod and locked the shutter open during the total lunar eclipse of March 3, 2007. The resulting image records the trail of the Moon (http://antwrp.gsfc.nasa.gov/apod/ap001013.html) (and narrower trails of stars) sliding through the night. Reddish hues (http://antwrp.gsfc.nasa.gov/apod/ap070830.html) common during the total phase of a lunar eclipse, are evident along the darker, slimmer portion of the Moon trail. At least part of tonight's lunar eclipse (http://science.nasa.gov/headlines/y2008/ 13feb_lunareclipse.htm) will be visible in clear skies over (http://sunearth.gsfc.nasa.gov/eclipse/JLEX/ JLEX-NA.html) the Americas, Europe, Africa and western Asia. The eclipse lasts over three hours from start to finish (http://www.shadowandsubstance.com/), with about 50 minutes of totality. Tonight's eclipse is the last total lunar eclipse until December of 2010.
