Earth rotation - I shot a timelapse to illustrate it

As you know our planet Earth is spinning on istself, this is what we call the Earth rotation. The best way to be witness of thid fact is to take a look to an astral object and see it moving in the sky. You can look at the sun but it's more impressive to look at the stars because yiu see all the sky moving. Astro timelapses are perfect for that because you see the night sky moving at a high speed and the earth movement become clearer. However to make it even clearer we can fix the sky and see the earth moving instead. This is what I tried to do here.

To do it we just need to use an equatorial mount to make the DSLR following the sky. Here I used the Star Adventurer mount. The timelaspe has been shot in the Cosmodrome Observatory in South of France at the end of august. You can see the Milky Way core being hidden by the Earth rotation.

Equipment : Canon 6D - Star Adventurer - Sigma ART 20mm
Settings : ISO-3200 - F2.2 - 30 sec

P.S. : did you spotted the bug on the lens at the begining ?
