The Astronomy Photographer of the Year 2024 competition is now open for entries, the Royal Observatory Greenwich has announced.

It’s time to put the finishing touches to your best astro images if you want to be named the winner of the Astronomy Photographer of the Year 16 (APY 16) competition.

With a grand prize of £10,000 on offer, the world’s biggest astrophotography competition – now in its 16th year – is open to both expert astro imagers and newcomers alike.

Each of the competition’s eight main categories covers a different astronomical subject – from our nearest celestial neighbours to the most distant objects visible.

If your image was taken after 1 January 2023, then all you need to do is pick which category it best fits and submit it. 

The best image in each category will take home £1,500, with the Runner-up and Highly Commended winners receiving £500 and £250 respectively.

If you’re a newcomer or prefer to process data from professional telescopes, then you could also be in the running to nab one of two special prizes worth £750 each. 

Younger astronomers needn’t feel left out either, as the Young Astronomy Photographer of the Year competition is open to all entrants under 16 years old.

Young entrants can enter for free and could take home the main prize of £1,500.

With entries now open for Astronomy Photographer of the Year 16, choose from the categories below and submit your image to the 2024 competition.

Categories

Planets, Comets and Asteroids

Taken with a Sky-Watcher 400P (16”) GoTo Dobsonian Reflector telescope, Baader Bessel (U)BVRI and ZWO IR850 filters, ZWO ASI462MM (Early-Bird) camera, 8,750 mm f/21.5, 5,000 x 5.9-millisecond IR exposures (29.5-second total exposure), 7,500 x 13.9-millisecond UV exposures, (104.25-second total exposure): 133.75-second total exposure

It’s been a great time for Solar System observers, with a parade of planets and several good comets visible throughout the year. If you managed to get a good astrophoto of one of our planetary neighbours, enter it into this category. 

Skyscapes 

Grand Cosmic Fireworks © Angel An. Location: Lake Puma Yumco, Tibet, China. Winner, Skyscapes category. Taken with a Sony ILCE-7S3 camera, 135 mm f/1.8, ISO 12800, 4-second exposure

To those of us on the ground, the night sky can sometimes seem a distant, isolated thing. This category brings the two a little closer by showcasing landscapes alongside celestial objects, and is one of the contest’s most popular categories.

Aurorae

Recently, the Northern Lights have been seen further south than they’ve been in 20 years, thanks to intense geomagnetic storms. If you’ve captured either the aurora borealis or australis, you could take home this hotly contested prize.

Our Moon 

Mars-Set © Ethan Chappel. Location: Cibolo, Texas, USA. Winner, Our Moon category. Taken with a Celestron EdgeHD 14 telescope, iOptron CEM70 mount, Astro-Physics BARADV lens, ZWO ASI462MC camera, 7,120 mm f/20, multiple 15-millisecond exposures

The changing face of our nearest neighbour offers no shortage of photo opportunities. Its cratered surface offers chances for close-up imaging, while its passage across the sky shows the motion of our Solar System in action. 

People and Space 

Zeila © Vikas Chander. Location: Heintesbaai (Henties Bay), Erongo Region, Namibia. Winner, People & Space category. Taken with a Nikon D850 camera, 135 mm f/2.8, ISO 200, 30-minute exposure.

Stargazing connects us. From our ancestors back through time, to those on the other side of the world today, we all look up at the same sky. This category explores that connection in images that juxtapose humanity with the vast Universe.

Our Sun 

A Sun Question © Eduardo Schaberger Poupeau. Location: Rafaela, Santa Fe, Argentina. Winner, Our Sun category. Taken with a Sky-Watcher Evostar 150ED DX Doublet APO refractor telescope, Daystar Quark Chromosphere filter, Baader ERF frontal filter, iOptron CEM70G mount, Player One Apollo-M Max camera, Gain 100, 840 mm focal length 120 mm aperture, 2 panels of 115 x 3.47-millisecond exposures

Not only did last year see the Sun rapidly heading towards the most turbulent time in its 11-year cycle, but it also included the most watched annular eclipse in recent memory. This year’s Our Sun category should be a particularly exciting one.

Stars and Nebulae

Taken with an ASA Newtonian 500 mm telescope, ASA DDM85 mount, FLI ProLine 16803 camera, 1,900 mm f/3.8, 890 x 1,200-second exposures, 672 x 300-second exposures and 15 x 1,800-second exposures

To the naked eye, stars appear little more than points of light and nebulae are faint smudges. Astro­photography transforms these objects into fantastical playgrounds of colour and intricate structure. Any image capturing them belongs here. 

Galaxies

Andromeda, Unexpected © Marcel Drechsler, Xavier Strottner, Yann Sainty, Location: Near Nancy, France. Winner, Galaxies category and overall winner. Equipment: Takahashi FSQ-106EDX4 telescope, Sky-Watcher EQ6 Pro mount, ZWO ASI2600MM Pro camera, 382 mm f/3.6, multiple exposures between 1 and 600 seconds, 111 hours total exposure

Collecting the light from these distant, vast targets is a challenge on its own, but processing them into works of art takes great skill. If your talent lies in capturing these distant cities of stars, enter your best work into this category.

Young Astronomy Photographer of the Year

The Running Chicken Nebula © Runwei Xu and Binyu Wang. Location: El Sauce Observatory, Río Hurtado, Chile. Winner, Young Astronomy Photographer of the Year. Taken with an ASA N20 f/3.8 Newtonian telescope, ASA DDM85 mount, FLI Proline 16803 camera, 1,900 mm f/3.8, 5.5 hours total exposure

Just because you’ve started astrophotography at an early age doesn’t mean your work can’t be absolutely spectacular. This special competition is open to any entrants under age 16, to showcase and encourage the great photographers of tomorrow.

Patrick Moore Prize for Best Newcomer

You don’t need high-end equipment and years of experience to get started in astrophotography. If you’ve just started your night-sky photography journey in the last year, then this special prize gives you your chance to shine.

Annie Maunder Prize for Image Innovation

The night sky should be open to all, which is why many professional observatories make all their data open access. This special prize asks you to take that data and process it in a striking and innovative way.
It’s a real chance to let your imagination fly!
