Oh my, that is SO cool!
How long was it in front of the sun? I'm guessing they didn't have much time for that shot...
What they did was to calculate the precise moment when the ISS would cross the surface of the sun as viewed from their lattitude and longitude. This is a lot easier now than when I had to do that sort of thing with a slide rule. Then they get a gps reference for exact timing. They started exposures a second before the anticipated transit and shot 14 frames as fast as the camera would process them. They used a Canon Rebel. Other than the timing, a new Canon camera, and the 6 angstrom filter, the shot is fairly low tech.
Yea right. Predicting a transit within a second... low tech
A digital camera that can shoot 14 shots within the space of 3 seconds... low tech
A 6 angsrom filter that someone can actually afford... this is freakin unbelieveable.
We live in an amazing world folks. It is astounding how wonderful it is to live in this time and place.... while we still have the ability to have a grasp of how all this stuff works. There will come a time when it will take a specialist to actually know how a clothes iron works.
