Quite an obvious choice of name for this image....
I learned the hard way how difficult it is to stand absolutely still for 25s and point to the stars, after quickly climbing a rock, while your cameras self-timer is relentlessly counting down the seconds.
Furthermore, the headlamp needs to point in the right direction: The beam may neither touch the arch, nor the arm or hand, as this hopelessly overexposes those sections of the image.
I eventually pulled it off, but don't ask how many tries I needed.
And when I finally did everything right, I probably stood there like an idiot for at least a minute, not knowing when the 25s had elapsed.
Sometimes a louder shutter would be an advantage...
