According to Wikipedia, the April 2015 lunar eclipseâ€”lasting only 4 minutes and 43 secondsâ€”is the shortest lunar totality since October 17, 1529 (486 years). The sequence in this image begins two hours after the moon first touches the outer shadow (penumbra) of the earth, and one hour after the moon crosses into the inner shadow (umbra) of the earthâ€”and continues through moonset, covering a total of 2 1/2 hours. This is my freshman outing in shooting a lunar eclipse. I have stacked images together once before for a star trail shot, the lunar eclipse was not quite as straightforward for post-processing (41 images blended, masked, and adjusted for exposure). We were fortunate to be able to witness this special event, not only for the uniqueness of the eventâ€”which is not slated to be this short of a totality until the year 2155 (140 years)â€”but also to have mostly clear skies until a bit of marine layer crept in as the moon was setting.
