The three brightest stars – Vega, Deneb, and Altair – will form a dominant summer-autumn triangle in the July sky. Alexander Alekseev, a researcher at the Tsiolkovsky State Museum of the History of Cosmonautics, told RIA "Novosti" that the optimal observation window will last approximately from 11 PM to 2 AM – only during this period does the sky become dark enough.
Alekseev clarified that the triangle is formed by the brightest stars of the constellations Lyra, Cygnus, and Aquila. During the dark period, with binoculars or a small telescope, deeper objects become visible: the Ring Nebula in Lyra, the globular cluster M13 in Hercules, and the Andromeda Galaxy. All of them are accessible to amateur optics without professional equipment.
July nights remain bright, so the observation window is limited to three hours, but it is precisely within this window that the main summer astronomical picture is concentrated. For a city dweller from a balcony or a dacha plot, this is a rare chance to see both a classic asterism and deep-space objects – from a planetary nebula to a neighboring galaxy – without complex preparation.
