The Geminid meteor shower has already started appearing in the night sky. It occurs between November 19 to December 24, 2022, but will peak on the nights of December 13 and 14, 2022, where you could see up to 150 an hour.
With the right astrophotography tools (opens in new tab) it’s possible to photograph shooting stars on any night of the year. But meteor showers like the Geminid bring lots of opportunities for stunning night sky photography (opens in new tab). Keep your camera ready if you want to catch a glimpse of this stunning shooting star display, and read our tips below to get the best meteor shots.
We’ve mentioned that the Geminid meteor shower will start in the next week, but what exactly is the shower, and when is the best time to photograph it?
What is the Geminid meteor shower?
A meteor or ‘shooting star’ is essentially just dust. Earth’s orbit of the Sun often takes it through stacks of debris left in the solar system by comets and asteroids. Mostly it’s just dust particles – no bigger than grains of sand – that Earth’s atmosphere slams into. As it does, these particles energize briefly and become disintegrating meteors.
Royal Museums Greenwich (opens in new tab) shares that, apart from the Quadrantids, the Geminids are the only major meteor showers not originating from a comet. As Space.com explains (opens in new tab), “the Geminids are the product of an asteroid. The reliable shower produces bright meteors associated with the asteroid Phaethon, a strange blue rock that acts like a comet.”
Although the Geminids are thought to be getting brighter each year, this year they’ll have to compete against interference from bright moonlight, which could make them harder to see and photograph.
When is the Geminid meteor shower?
As mentioned already, the Geminid meteor shower has already started appearing in the night sky. It is generally a reliable annual shower, and in 2022, it will peak on the nights of December 13 and 14.
How to photograph the Geminid meteor shower
A meteor shower typically only lasts a split-second – though occasionally as long as a second – as it streaks across the night sky. That doesn’t give you enough time to react to it, so your camera’s shutter needs to be already open, ready, and waiting for the light from a shooting star to hit its image sensor. That means you’ll need to use long exposures of up to 30 seconds or beyond.

The right location
In terms of location, picking a site with little light pollution is important because you’re going to be opening the shutter for at least 25 seconds, so a lot of light is going to get in. This interactive world light pollution map (opens in new tab) and the Dark Site Finder (opens in new tab) are both very useful for scouting a good location away from the bright lights of urban areas. However, if you can’t travel outside a city, you can still try to photograph shooting stars. Find somewhere where no streetlights are going to interfere with your composition, and get your camera into the shadow of a building.

Although the darkest skies are between midnight and dawn, the radiant of the Perseids – the constellation of Perseus – is ‘up’ right after dark in the northern hemisphere, so you can start looking for shooting stars right away. Or, while you wait for the night skies to darken, you could try to capture a beautiful crescent moon just above the southwestern horizon before it leaves the sky.
The right gear
(opens in new tab)
Our best astrophotography tools (opens in new tab) buying guide has you covered for all the gear you’ll need to photograph the Geminid meteor shower this year. However, here’s a quick overview for the key kit you’ll need…
You can use any DSLR (opens in new tab) or mirrorless camera (opens in new tab) as long as it has a manual mode, and you can shoot long exposure images for at least 30 seconds. However, one of the best full-frame cameras (opens in new tab) is the best option because it will capture more light and feature less image noise when used at high ISOs.
Since you want to capture as much of the night sky as possible to maximize your chance of capturing shooting stars, a wide-angle lens is best. The best lenses for astrophotography (opens in new tab) have an effective focal length of between 10mm and 28mm.
Keeping your camera steady is an absolute must for long exposures, so you’ll need the best tripod (opens in new tab) you can get. If it’s windy, don’t use the tripod’s extension arm. Check that the horizon is level before taking a shot.
A shutter release cable (opens in new tab) that can be locked, or an intervalometer or remote control, will be helpful for taking repeated long exposures without having to manually depress the shutter button every 25 seconds.
The right composition
Although it’s tempting to point your camera at the radiant, meteors can just as easily appear anywhere in the sky.
By pointing at the radiant you’ll likely miss as many meteors as you’ll catch, so it’s better to get something interesting in the foreground – perhaps an old barn, a tree, or a sculpture – in your composition to add interest. That way you’ll have a beautiful landscape photo that will hopefully feature a shooting star or two.
Taking the shot
With your lens’s focus set to infinity, and its aperture to around f/2.8 (or as open as possible), choose ISO 800 or ISO 1600 (or even higher if you’re in a really dark sky site) and fix the shutter speed to 25sec. Take the shot, and if you’re not happy with result as a stand-alone image, make adjustments and re-take.
Once you’re happy, here comes the fun bit; take the same shot 50-200 times in Raw over the course of an hour, or a couple of hours. Just be careful not to switch-on any lights, or nudge your tripod during the shooting period; keep dark and stand well back.
Either way, you’ll end up with hundreds of shots of the night sky, some of which will hopefully have shooting stars within them. If that’s all you’re after, you can extract the images that do feature a shooting star and ditch the rest. However, if you use the free software StarStaX (opens in new tab), you can drag-and-drop all 200 photos into it to create a star-trail (opens in new tab) image … featuring shooting stars, of course. It’s also possible to do this on Adobe Photoshop.
