Explanation: With roots in a rotating planet, an old tree is centered in this sequence of 137 exposures each 20 seconds long, recorded one night in northern Sicily. Digital camera and fisheye lens were fixed to a tripod to capture the dramatic timelapse, so the stars trailed through the region's dark sky. Of course that makes it easy to spot the planet's north celestial pole. The extension of Earth's axis of rotation into space is toward the upper left, at the center of the concentric star trail arcs. The Milky Way is there too. The plane of our galaxy stretches across the wide field of view from north to east (left to right) creating a broader luminous band of of diffuse starlight.
For more detail go to the link and click on the image for a high definition image. You can then move the magnifying glass cursor then click to zoom in and click again to zoom out. When zoomed in you can scan by moving the side bars on the bottom and right side of the image.
That is a cool picture!

Hey MtnClimber:
I’ve been meaning to ask you, do you have telescope rig?
I had a Meade 8” about 5 years ago but I sold it after a year or two of close to zero clear skies in Colorado Springs as soon as I got it.
I don’t have a telescope. I need to get one. I am an electrical engineer and did lots of work on satellites and large satellite ground stations. I even consulted a small amount on the Webb Space Telescope. I have my interest from those things.
Some of these APOD’s are taken with just a DSLR, which I’d like to get more into that as well.
