Many of you know this, but for those of you who are not night photographers, in the northern hemisphere, in summer, on a moonless day and away from the cities, we can see the Milky Way visualizing the galactic center on the horizon to our right.
On the other hand, in the southern hemisphere, in our summer (and therefore its winter), the Milky Way can be seen showing the galactic center right in the middle of the arc and at the zenith of the sky, above our head. So the arc of the Milky Way is much more impressive and the galactic center much cleaner.
The sky is composed of a panoramic of 37 tracker shots, each of them 5 x 30s f2.2 ISO 800 - with the Sony GM 35mm f1.4 .
The earth is a panorama of 10 shots at 16mm.
