Ralf Rohner is known for capturing amazing time-lapse photography - from shots of the Milky Way to stunning night landscapes, his images can be mesmerising.
Recently Rohner recently put his time-lapse skills to use to create a video taken during a return flight from Bangkok to Zurich.
In an Instagram post, Rohner said that wasn't the plan initially.
"I wasn't planning to do a time-lapse but was aiming for sharp stills. To have a reasonable chance to capture enough exposures with pinpoint stars that allows me to stack the sky, I nevertheless have to capture a rather long sequence," he said.
"I therefore decided to stitch the sequence into a time-lapse movie."
The first part of the video shows moments from the eastbound flight with highlights including a clear view of the Milky Way and active thunderstorms in the region of Lucknow, India.
The second part is comprised of footage from the return flight, again over India. Due to the westbound track, the Milky Way is only visible at the very left edge of the frame, where the Southern Cross and the stars Alpha and Beta Centauri are slowly setting below the horizon.
Rohner does sell his images through his website, but if you're into photography and want to know what technology he used and what the settings were, he shared that information too:
EXIF, Canon EOS Ra, Samyang 24mm f/1.4 @ f/2
Mount: Boeing 777-300ER
1'100 exposures of 5s @ ISO6400
