I took a chance at GIFing / time lapsing the setting sun for the first time EVER and boy did I ever get lucky! First, it was a hazy, summer-like evening even though the temperature was 53F but it enabled the sun to not be too bright for the camera to handle. Secondly, my tripod was occupied by my other camera as I was making a more general sunset time lapse as well. Then, in the middle of this ~5 minute GIF, while balancing my camera on a fence, a distant airplane flies Right across the middle of the solar disk! This is exactly how it happened; the only changes were slowing down this part.
If used, please do give credit. These are not easy to make and require about 4-5 hours of work and I can assure you, finding GIFs like this on the Internet is not a common thing so I will know if you take it!!! Thank you
