An image with a circular frame, with somewhat psychedelic colours. In the foreground there's a tall tower with criss-cross metalic beams, standing on a gravel ground. In the background there are several cylindrical buildings. Curved luminous bands are spread across the sky, as if painted with a brush.

   1/ This is the longest exposure I've ever taken: 8 months long! It shows the Sun's path on the sky between Apr 17 - Dec 11 2018, as seen from ESO's Paranal Observatory in #Chile.

   This is part of a collaboration with Diego López Calvín, an expert in solarigraphy: https://solarigrafia.com

   Diego sent me some of his hand-made #pinhole cameras, which I placed all over Paranal. So what do we see here? See thread below 👇
