OK, this is just fooling around, it doesn't mean anything, but an eyecatching view anyway. What would the great mountain ranges of Helene look like from a viewpoint on the opposite side of the valley?

Just for fun: Assuming a free-fall drop of 2 km and using Helene’s gravity figure below (1/5000th that of Earth’s), ballpark figures for your skier’s terminal velocity speed would be less than 10 km/h after a 20 minute run-out

Great work. And in way I'm even more impressed by the enhanced color composite than the movie since it can be extremely difficult to perfectly align the color channels for closeups of an irregular, small target like Helene.

Fan-TASTIC, Daniel!!!! Oh my goodness, that is unbelievable. Simply beautiful. Great work, Machi! Thanks! Great work. And in way I'm even more impressed by the enhanced color composite than the movie since it can be extremely difficult to perfectly align the color channels for closeups of an irregular, small target like Helene. It's never perfect for irregular bodies, but it can be done with ImageJ + UnwarpJ or via manual warping. I used both methods in this animation. -------------------- |
