Finally, I have found a must-have piece of camera gear that makes any camera body, even the astronomical D4 and 1D Mark IV, look oh-so affordable. At least, that's the angle I'm taking in the current round of equipment purchasing negotiations with my business manager (and spousal unit).
The must-have equipment? The International Space Station. Gotta' get myself one of those.
Crew members on board have created a number of amazing videos. My favorites show the Milkyway and Aurora Borealis from low Earth orbit. (This one is the most creative. NOTE, slow-to-load.) These videos (and descriptions of what you're seeing), which are posted on this NASA website, are unlike anything I've ever seen - and unlike anything I'll ever get to photograph, according to my business manager.
All of these videos are worth a look, but they are short, silent clips. Fortunately, Earth-bound photographer Alex Rivest had the good graces to edit together many of these shorts into one long video (top of post) complete with music.
