Description

The reason of this picture is just to show the NCP rotation (visible in full resolution) in north hemisphere without star trails, using just a camera, a tripod and stacking.
It was my first approach with astrophotography, I was really really novice in everithing about the night sky, so I'm sure it's easy to do better for anyone!
I hope nthis can be useful.
