Here is an image Flickr will likely butcher. It's a horizon-to-horizon "vertorama" of the Milky Way taken with Galen's Arch (aka Mobius Arch) in the foreground.
Some green "airglow" is pretty obvious on both horizons.
Mind you this is a little "crunchy" from being downsized from 14,215 pixels tall to 2048. We could have left this as a horizontal panorama... but then you'd have to look at Galen's Arch sideways. Galen's Arch in Alabama Hills, California, is more commonly called Mobius Arch, but I prefer to call it by the name of the photographer who brought it to public knowledge and inspired legions of landscape photographers: Galen Rowell. Galen's legacy lives on in his son Tony Rowell.
The orange glow at the top is from the town of Lone Pine, California.
This is a photomerge using 10 separate photos.
