Explanation: The sky toward the centre of our Galaxy is filled with a wide variety of celestial wonders, many of which are visible from a dark location with common binoculars. Constellations near the Galactic Centre include Sagittarius, Libra, Scorpius, Scutum, and Ophiuchus. Nebulae include Messier objects M8, M16, M20, as well as the Pipe and Cat's Paw nebulae. Visible open star clusters include M6, M7, M21, M23, M24, and M25, while globular star cluster M22 is also visible. A hole in the dust toward the Galactic Centre reveals a bright region filled with distant stars known as Baade's Window, which is visible between M7 and M8.
