Your First Night Sky
The Moon, the Orion Nebula, and the Andromeda Galaxy are all visible without any equipment. A pair of 7×50 binoculars or a small 70 mm refractor opens up Jupiter's moons and Saturn's rings. This guide covers what to look for and how to start.

The Moon, the Orion Nebula, and the Andromeda Galaxy are all visible to the unaided eye.
The Moon orbits Earth at an average distance of about 384,400 km. Its dark plains (maria) and large craters are visible in ordinary binoculars, and even without them the phase and terminator line are easy to see.
The Orion Nebula (M42) lies about 1,344 light-years away and appears as a fuzzy patch under dark skies. The Andromeda Galaxy (M31), about 2.5 million light-years away, is the most distant object visible to the unaided eye.
This guide was compiled from established facts about beginner stargazing: instrument specifications, known distances to celestial objects, and the Bortle scale for sky darkness. Each claim is tied to a verifiable measurement or a well-known observational fact.
