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!

Fantastic video, JC. Also loved the music.
Take care now.
Kind regards.
Liz.
Thanks so much for view and kind words =) I hope you're having a great week!
Great shots
Thanks a bunch for watching! =)
Thanks for sharing all the information and video/music, well done my friend.
Thanks for watching and commenting - have a great week! =)
Another lovely video. Great close ups of the moon. I think the clouds made it interesting. I'm thinking of getting a moon globe. BTW I'll be visiting San Fransisco coming this weekend. It's too bad it's off season to see the wild cucumbers.
May would definitely be better. There has been a LOT of rain this year - so it should be a good season for them... just going to take a while for them to get growing. Have a good trip! =)
@@jcmegabyte Well I'll probably be back again later in the year. This trip was arranged for me. But I'm looking forward to other cool plants out there.
What a great show!
I'm happy you enjoyed - thanks for stopping by! =)
Fantastic video
Thanks so much for watching, cheers!
Is it possible that some bodies get source of light from other stars n sun like stars? N they not shine partial bt full n it create illusion for our eyes n technology.
Starlight from the night sky is capable of lighting celestial objects, but is generally so weak that any bright nearby light source overpowers it almost completely. However, during the time when the Moon is only a very thin crescent, the "dark" part of the moon can still be seen (although very dimly) due to being illuminated by sunlight reflected from Earth - which is sometimes called "Earthlight". Long exposure photographic techniques can capture objects very dimly lit by celestial light sources other than the sun, but it requires that the equipment's focus stays locked onto the subject for long periods to capture enough light, which is not always so easy to do. Thanks for watching and commenting!
JCMegabyte. Thanx 4 ur knowledge n effort dat u made 4 an unknown person to write a paragraph. I appreciate it.
