This image is an unprecedented star trail image taken from the Equator (this imaginary line that splits the Earth into the two hemispheres) in Ecuador (the country). If you stand on the Equator line you can see the Southern Pole at the horizon to the South (left of the image) and the Northern pole at the horizon on the opposite direction. The Earth rotation will make all the sky and stars look like they rotate around these two points, making them appear as concentric circles (which look like ellipses on this distorsioning fish eye image). Note that on this image, that cumulates 10 hours of exposure starting 1 hour after sunset and finishing 1 hour before sunrise (nights and days always last 12 hours on the Equator, it is a permanent equinox) , more than 90% of the sky is 'visible', this is another particularity of being on the ecuator line : you can observe the largest part of the sky during any night. An extremely bright meteor appeared during that night and seems to be pointing at the Southern Pole (extreme left of the image).
