The Night the Sky Went a Little Crazy

Airglow was invading the night skies on this night. Much like in my previous timelapse looking to the West, the airglow just went a bit psycho. I now not many will like this, but airglow is real, and this is what it looks like. I remember the first time I came across it years ago when I saw shooting the Milky Way up in Yellowstone, I spent hours trying to process out the green and magenta casts out of the night sky because I had assumed something went wrong with my capture. Only later did I find out about airglow that it's a natural phenomenon. I then slowly began to accept and then embrace airglow over the years.

So my last timelapse was looking West, this one is looking to the East specifically to catch the Milky Way. This camera I had walked back maybe close to a half mile from the road, across a rock scattered field (that I had to walk through in the dark once an hour to check on the camera), down behind a hill in hopes of getting away from all lights from passing cars. For the most part I succeeded. It didn't help that in the middle of the night a car stopped about a mile down the road (I was up on a rise) and these 2 people got out and spent the next several hours with powerful flashlights just walking around the hills and shining their lights, waving them all over looking for who knows what? I don't know what they were looking for and what they would have done with what they were looking for when they found it. I had just wished they had found a place that wasn't so close to where I was.

The night sky was captured pretty normal, ISO 3200, 25 sec exposures at f2 with the Nikon D850 and the Sigma 14mm f1.8 lens. I set the exposure manually in the camera and just locked in my remote to trigger shots all night long. It is made up of 1535 images. I have a dummy battery and small little portable power supply that lets it run all night without my having to worry about batteries running out.

This is just north of Furnace Creek in Death Valley looking to the East.

I hope your well. This is really neat and fun to see all the shooting star's.
Excellent job !
As we say back east- embrace the airglow and let it flow :)

Unusual colors in the glow. Was any of this visible to the named eye while you were out there shooting this?

Hey Ben, it's great to have you check in!

How is the food at Milts? I have never eaten there but I am thinking I want to next time.

These are the normal airglow colors you will see when there is airglow, green and magenta.

Nope, you can't see it by the naked eye, it takes the longer shutter speed of the camera to absorb it in. So yeah, you never know really if you have it or not when shooting, you only find out later. :)

Nice work, the stars are magnificent. Too bad about the flashes of car lights that distract, but that can't be avoided in that location. I would slow down the zooms so that the viewer hardly notices them at first.

Jim,
This is a very interesting observation. I have also noticed the green/magenta in some Milky Way images. I also spent time processing that color out. Do you know what causes this problem? I usually process it out because it is not what the normal eye sees and I don't like the green color in the sky. However, it make a very neat time-lapse video.

Loved this and all the work involved in getting it. I have not shot any night photography except the moon on occasion and really appreciate all the technical work you all do in capturing the night sky. Beautiful.

Thanks Jim. Yeah, watching it now, I had the same thought about the zoom speed, that it should have been a little slower to make it feel smoother. Next time. :)

Hey Bob, thanks so much!

I no longer consider Airglow a problem. :) so I have stopped trying to get rid of it. Probably since I now have seen it and captured it for so many years, I have come to accept it and embrace it.

From Wikipedia: Airglow is a faint emission of light by a planetary atmosphere. In the case of Earth's atmosphere, this optical phenomenon causes the night sky never to be completely dark, even after the effects of starlight and diffused sunlight from the far side are removed.

So give it time… Airglow will grow on you. :)

Hey Jim, when Sonny showed up, he said he did not need any lunch, so we just took off. The food was pretty good the last time I ate there.

JIm,

OK< THAT was spectacular. I love that airglow - it is mesmerizing, and adds some interesting color. And the Milky Way portion of this is great as well. It looks like you have nailed the exposure settings. I have rented that lens for my Hawaii trip and hope to do something from Haleakala NP with it. I think I will also see how I get on with ISO 3200, F2 and about 25 seconds or so if I manage to be able to set up and do anything. I also need to buy a cheap intervalometer/remote shutter release so that I can do that same trick to lock the shutter button down, and make sure the images have essentially no gaps.

What is the pacing for the 1535 frames, is this 24 fps, 30 fps, or ??? I find the result to be about perfect. And I really like how you included both the pre-sunset and the post-sunrise frames. I am assuming you had to change exposure somehow for those portions of the time-lapse? Was that automated or did you manually make those changes? Results are epic in any case. One of my very favorites from you for this type of work - and that is saying something, as you have such a great amount of stellar (pun intended) nightscape work.

I love this one Jim, beautiful work and I really like the piano piece you chose. You seem to really be getting the process down, and I see venturing into this realm soon myself.

Sweet time lapse video, Jim.
