Description

Canon 6D first light on the Black Sea coast 28th of July 2022
The shooting took place low above the horizon over the water, but there was no moon and clouds that night. The molecular cloud of Ophiuchus Rho is the closest region of star formation to Earth. The cloud is located between the constellations Ophiuchus and Scorpio. Due to the high density of hydrogen and dust, the cloud does not pass either the ultraviolet, visible, or infrared ranges of electromagnetic radiation, which is why we see it as dark spots. Due to the fact that stars have already formed and lit up there, we see a cloud illuminated in different colors. Stars emit a wide spectrum of EM radiation, the color of the star indicates its temperature - the higher, the colder. 400 years light years from Earth. In addition, you can see the nearest star cluster- M4 (7000 light-years), as well as M80. Some star systems are double (22 Scorpions, Rho Ophiuchus, Antares)
