– how do stabilised cameras work? Particularly when taking photos of the earth’s rotation?

129 views

I’ve seen a few videos of Timelapse photography of the night sky and the earths rotation. The notes explain that it’s made with a stabilised camera, but I can’t get my head around how that would work! Somebody please eli5!!

The gears in the mount rotate to match the speed that Earth rotates. By aligning to the north star, Polaris, which is in basically the same spot every single night (very, very minimal movement), the mount can then match the rotation of the Earth to counter its perceived movement. Here is a visual for it:
