Phone-first astrophotography
Mobile astrophotography with a smartphone
You can start taking night-sky photos with the phone already in your pocket. The biggest improvements come from keeping the phone still, choosing a bright target and learning how its camera handles low light. Camera controls differ between phones, so use the closest equivalent setting available on yours.
Start with a steady phone
- Rest your phone on a firm surface or use a tripod and secure phone clamp. Set a two-second timer or remote shutter so tapping the screen does not shake the shot.
- Use the main camera lens and avoid digital zoom. Clean the lens, frame the target, tap to focus, then lower exposure if bright details look washed out.
- For stars and constellations, try your phone’s Night Sight, night mode or long-exposure mode. Keep the phone still throughout the exposure; if stars become short streaks, use a shorter exposure.
- Start with the Moon, bright constellations or a wide view of the night sky. Very faint nebulae and galaxies are harder because phone sensors collect much less light than dedicated astronomy cameras.
Taking pictures through a telescope
For a first try, photograph the Moon through an eyepiece. A phone-to-eyepiece clamp helps line up the camera with the small bright image. Centre the Moon in the eyepiece first, then move the phone slowly until the circular view fills the screen. Reduce exposure to keep lunar detail from turning white. Avoid holding the phone by hand against the eyepiece, and do not use this method on the Sun.
What to expect
Phone night modes often combine several exposures, so they work best when the phone is braced and the scene stays still. City lights can wash out faint stars; choose a darker, open view when you can. A phone is a useful way to practise framing and capture the Moon, constellations and bright sky scenes before deciding whether you need more equipment.
For more ideas, browse the target catalogue and check the astrophotography weather forecast before a session. Never point a phone, telescope or camera at the Sun without a certified solar filter fitted securely over the front of the optics.
