## Description

Point at the sky: constellations where they really are, and when their light set out. No internet, no account, no ads.

Old Light is a precision star atlas that never compromises on the astronomy. Hold your phone up to the night sky and stars, planets, and constellations appear exactly where they are.

■ Precision you can trust
Sun, Moon, and planet positions are computed to arcsecond accuracy using professional models (VSOP87 planetary theory, Meeus algorithms), corrected for your exact location with atmospheric refraction and parallax. Labels land right on the real objects.

■ Fully offline
9,000+ stars, all 88 constellations, and 110 Messier deep-sky objects are built in. It works flawlessly in airplane mode, or deep in the mountains with no signal.

■ AR — stars over the real sky
Turn on the camera and the stars and constellations overlay the actual sky in front of you. Or use sensor pointing to see the sky in the direction you're holding your phone.

■ What's up tonight
The Tonight list shows the planets, Moon, and bright stars up right now with their direction and altitude. Search for any object and follow the arrow to find it.

■ Famous objects in photos
Admire Saturn, Jupiter, the Andromeda Galaxy and more in real NASA imagery — and the Moon rendered in tonight's exact phase.

■ And more
· Precise coordinates (RA/Dec, Az/Alt) with rise, transit, and set times
· Time travel to any night, past or future
· Red night mode to protect your dark adaptation outdoors
· Constellation names and stories

No ads. No in-app purchases. No account. Just the night sky, precisely.
