Binoculars for the eclipse

Like everyone else, I am getting ready for the total lunar eclipse, tomorrow night, and, wonder of wonders, the forecast is for clear skies in my area. Okay, what do I use for observing lunar eclipses? Well, a binocular, of course. An astronomy binocular is best, but any binocular will do. Use what you have. A good binocular not only brings the eclipse up close and personal, a good binocular will also enhance the color of the moon during an eclipse. The color is a result of light "leaking" into the shadow the earth casts on the moon as light gets bent when it passes through the earths atmosphere. It is colored since earth's atmosphere acts as a filter and some colors, mostly blues, don't make it through. Of course, this still leaves yellows, reds and browns, but as to which will predominate, no one can say for sure. Get your binocular and see for yourself.
