You can then either use them or discard them when you come to stack your images, thus creating a few different versions of your final shot. Once you have finished capturing your star trail images, consider taking a couple more using one-second bursts of torchlight on your subject to create different lighting effects. Tungsten white balance can help reduce the effects of any light pollution.

Set the lens to manual focus, then either pre-focus it to infinity (some cameras have a ∞ symbol on the lens), or shine a torch on something 20m or so away and focus on it using autofocus (then switch back to manual). “Always shoot in RAW format,” says Simon. “That way you can use Photoshop to reduce the noise and any light pollution.” Use a tripod, a wide-angle lens on the lowest aperture setting possible, and shoot at around IS0 800 to avoid too much noise. If you’re shooting multiple 30-second images to stack later – which you should if you’re using a digital camera – then the settings are the same as for any night-sky shot.

However, while a bright Moon does wash out a lot of stars, it’s perfectly possible to capture good-looking star trails even near the full phase. Just as important as avoiding light pollution is the position of the Moon. A lot of astro imagers have three weeks off every month and only venture outside during the week of a new Moon, when the slim lunar crescent rises late and sets early. Remember to follow current travel restrictions wherever you are, and stay safe at all times. Take a compass with you in daylight and you can plan your shot before it even gets dark. If you’re shooting under a southern hemisphere sky, point south at the Southern Cross (from March to September) or near bright stars Achernar or Canopus (from October to February). For more on this, read our guide on how to find the North Star. If you want to capture the classic ‘rotating sky’ effect like in the image above, in the northern hemisphere you will have to shoot north at Polaris.
