How to try deep-space astrophotography

The universe is back in fashion. Everywhere you look there are astonishing images of the night sky. Visit Instagram and you’ll see the Milky Way and the northern lights arching across the sky above beautiful landscapes, while NASA and the James Webb Space Telescope fill the internet with close-ups of exoplanets and galaxies far, far, away.

You might think that creating images of the night sky is limited to what you can see with your own eye, but not so. Want to go deeper into the cosmos? There are two ways to photograph star clusters, nebulae, galaxies, and other deep-sky objects; using a tripod-mounted star tracker underneath your camera, or attaching a camera to a telescope.

The best star tracker camera mounts are simple, portable devices that go between a tripod and your camera. Some of the most popular models are the Skywatcher Star Adventurer and iOptron SkyTracker, costing around $320/£250.

They’re called ‘equatorial’ mounts because they have a motor that moves them in sync with our planet. As our planet rotates, the stars appear to move – as captured by a star trail – and these mounts counteract that. Aligned to Polaris (also commonly known as the North Star), they correct for your exact position on the planet, allowing you to take long exposures of faint objects without blur, therefore collecting a lot more light. You can take 90-second exposures with lenses as large as 600mm, though wide-angle lenses allow even longer exposures (up to ten minutes on the Milky Way).

Another technique that is useful if you have access to a deep-space telescope is to attach your camera using a T-Ring and 1.25-inch or two-inch adaptor (unique to your camera and available relatively cheaply online). You can then insert it where the eyepiece usually goes, and use the magnification of the telescope to take shots.

Either way, stick to a wide aperture and ISO 800-3200 (depending on your camera) and experiment with the shutter speed (always using a camera remote). You’ll then need to dive into photo-editing software to process your RAW images to produce bright, detailed, out-of-this-world images.

Lone stars don’t usually make interesting targets. An exception is the blue and red double star Albireo

A popular target for a camera on a telescope is the Andromeda galaxy (M31)

Star clusters like the Pleiades are perfect for capturing with a star-tracker mount
