How to start stargazing with your phone
You do not need a telescope to start. On a clear night away from street lights, your eyes and a star map app can show you planets, constellations and, with luck, the Milky Way. Much of the skill is choosing the right night and letting your eyes adjust.
A simple routine, then stargazing apps.
Choose the right night
Check the forecast for clear skies and the Moon’s phase; a bright Moon washes out faint stars. Compare moon phase apps to plan around it.
Get away from lights
Even a park or the edge of town is darker than a lit street. Turn away from nearby lights and give your eyes time to adjust before judging what you can see.
Point your phone at the sky
Star map apps show what is in front of you as you move the phone. Use night or red mode and low brightness to protect your night vision. For dark-sky walks, see how to navigate offline on a hike.
Build up from the bright
Start with planets and the brightest stars, then learn one constellation at a time. Binoculars are a cheap next step before any telescope. Compare apps in stargazing apps and star map apps.

Frequently asked questions
How do I start stargazing without a telescope?
Pick a clear, dark night, let your eyes adjust and use a star map app to find planets and constellations.
Why use red mode in a stargazing app?
Red light disturbs your night vision less than a bright white screen.
Does the Moon affect stargazing?
Yes. A bright Moon hides fainter stars, so nights near the new Moon are darker.
