The Rho Ophiuchi and Antares Nebula Complex

One of the most beautiful regions in the starry sky, a complex of molecular, cold (dark) gas-dust clouds and reflection, emission nebulae surrounding the stars Rho (multiple) Ophiuchi, Al Niyat, and Antares of Scorpius. Between them, slightly lower and to the right, the globular star cluster M4 is visible, located much farther from us than the complex itself, against the backdrop of numerous faint stars in the Milky Way's spiral arm. Captured over three nights: June 10, 11, 12, 2021. Crimea, lower plateau of Mount Chatyr-Dag, altitude 1020 m above sea level. Total exposure: 3 hours 12 minutes (160×60s + 130×15s), ISO 250.
