JCMegabyte's video: Total lunar eclipse 2019 Telescope and Timelapse V24849

The start of 2019 (January 20th) featured a "Super Blood Moon" - a total lunar eclipse when the moon orbits particularly close to Earth. Viewing conditions weren't looking so good due to partly cloudy skies, but fortunately there was enough clearing throughout the event to get some decent shots. So why does the "Blood Moon" glow reddish-orange? The reason is the same as why sunsets on Earth are often a beautiful red-orange color - "Rayleigh scattering" of light waves. As it turns out, Earth's atmosphere (about 78% nitrogen, 21% oxygen, and 1% other gasses/particles) is pretty good at absorbing and reflecting certain frequencies (colors) of light, while letting others pass more easily. Higher frequency/energy color such as violet, blue, and green is absorbed and scattered (sent off in different directions) by air molecules (which is also the reason why the sky appears blue) while lower frequency/energy yellow, orange and red light tends to pass more-or less straight through. This means that the more of Earth's atmosphere the light has to travel through, the more of the green-blue-violet colors are filtered out. So what does Earth's atmosphere have to do with the moon, and why is a "Blood Moon" different than a "normal" total lunar eclipse? ...During a "normal" total lunar eclipse, Earth's shadow more-or less passes directly across the lunar surface, shading it in complete darkness. However, if Earth's shadow only grazes the Moon, only sunlight which has passed through Earth's atmosphere (and has thus been filtered of most green-blue-violet light) makes it to the Moon, essentially casting a sunset onto the Moon! This would be an amazing sight from the lunar surface as well. The first segment shows an 828-frame time lapse sequence for the entire event as seen though a 17mm f/4.0 lens at 15 second intervals (Canon 5D Mk2). The following video clips show the progress of the eclipse as seen through an 800mm Celestron telescope with 2x optical teleconverter and Sony a7III mirrorless camera, attached to the telescope with a T-Mount adapter. While never really crystal clear due to the hazy high cloud coverage, the lower clouds managed to stear clear of the fully eclipsed disc a few times. A couple of panned still images taken with long exposure help show the Moon's detail. Conditions were soggy as temperatures fell, resulting in a heavy dew accumulating on just about every surface, making it necessary to use a home-made warm air blower to keep the Canon's lens from fogging up. The telescope fared a little better being partially protected by a short lens hood, but by event's end it was starting to fog-up as well and needed to be wiped by hand. I guess I'll have to make another blower!
