The dwarf planet and the nebula.

Four hundred years takes the light of the star Nu Scorpii to reach us, reflected in this blue nebula, a beautiful landscape in the Scorpius constellation.
Closer to us, about 30 light-minutes away, the dwarf planet Ceres orbits in-between the planets Mars and Jupiter, the first asteroid we met on January 1, 1801, inaugurating the nineteenth century, that time of great discoveries.
In this image they both share scene: the "faraway" nebula and the "near" asteroid that appears here as a white line at bottom-center of the frame, showing its orbital movement during the 7 hours that the exposure lasts (“slow” travel at speed of 18 km/seg that can be seen in the video).


This photography was taken in La Banderita observatory, La Pampa, Argentina with a total integration time of 5 hours 35 min.
The used equipment setup: Astrotech 65 mm F6.5 APO refractor, unmodified Canon 6D camera, Sky Watcher Star Adventurer mount (modified for DEC guiding) and homemade anti-dew system.
