Like John Dobson always said when you need to wake up early in the morning: drink a glass of lemonade before you go to bed -- you need to wake up to rotate your telescope mirror pitch lap or take it off the mirror while making a telescope mirror. The same goes for waking up for a predawn lunar eclipse! Set your alarms (weather permitting for before 5 a.m. Saturday morning! Our west coast gets a total lunar eclipse in the morning before dawn! My video chart shows a 12 minute totality (via USNO & S&T) but depending where you measure the deepest shadow (the umbra) some websites and most of the media are saying less than 5 minutes (THE SHORTEST ECLIPSE OF THE CENTURY). (caps on purpose) So I summed up the different calculation methods here. http://solarsystem.nasa.gov/news/whatsup-view.cfm?WUID=2026 <http://l.facebook.com/l.php?u=http%3A%2F%2Fsolarsystem.nasa.gov%2Fnews%2Fwhatsup-view.cfm%3FWUID%3D2026&h=aAQFtktTs&enc=AZMhuNzfsSnCxaTRydYIL-ihC3pjEwEQB1JMzRNy1xBXCqkuq0IexxMgIu9zMOi78I7NXYETBCZEgliAqaofDvq0bVaeoANkjclYicZOsrsf6IrFs4IVvrNIskzQ6FQohhbyPNmeW1uNbaqVVO2q4OTPzhgm7xhT3Fdq3pvX5pX7eg&s=1> Regardless, get your butt out of bed before 5am PT if you can. Totality is a few minutes before 5 am until a few minutes after 5 am. Pacific. Training for August 2017!
