Astronomy Photographer of the Year 2023 opens for entries


The time has come again for astronomy photographers around the world to put the finishing touches to their best images in the hopes of being named the winner of the 2023 Astronomy Photographer of the Year competition.

Hosted by the Royal Observatory Greenwich, the world’s biggest astrophotography competition is now open for entries from astrophotographers hoping to win the grand prize of £10,000.

Now in its 15th year, the competition has eight main categories for different astronomy subjects, each with a £1,500 prize up for grabs, as well as runner-up and highly commended awards of £500 and £250 respectively.

Read our beginner’s guide to astrophotography and learn how to improve images with image processing.

The top prize in the 2022 awards went to Gerald Rhemann for his image ‘Disconnection Event’, showing the tail of Comet Leonard being carried away by the solar wind.

There are also two special prizes of £750 each: one for the best newcomer, and one for using professional data in an innovative way.

Entrants under 16 years old can enter the Young Astronomy Photographer of the Year competition in the hope of winning £1,500, as well as a Celestron Astromaster 130EQ MD to help them continue their observations of the night sky.

An exhibition of the winning images will be on show at the National Maritime Museum, London, from 16 September 2023.

APY15 competition categories

Below are APY15’s 11 categories. You can enter each one multiple times:

Planets, Comets and Asteroids

It’s been a great year for Solar System observers, with a parade of planets visible as well as a number of bright comets. If you managed to get a good astrophoto of one of our planetary neighbours, enter it into this category.

The night sky can often seem remote, unconnected to us on the ground. This category aims to showcase landscapes or cityscapes alongside celestial objects in the same scene, and is one of the contest’s most popular.


The Northern and Southern Lights are some of the natural wonders of our world. Capturing their beauty requires persistence, skill and luck, so if you were fortunate enough to capture a striking aurora shot, you could take this hotly contested prize.

Our Moon

Our nearest neighbour is a wonderfully varied world. The craters and crags of the Moon’s surface offer opportunities for close-up imaging, while its changing phases showcase the clockwork motion of our Solar System in action.

People and Space

Stargazing is a unifying experience, linking the world as we all look up at the same sky. This category explores that connection, asking for images that show the impact of humanity juxtaposed against the vast Universe.

Our Sun

Cutting through the intense glare to photograph our Sun takes skill, but the results can be striking and dynamic. Last year gave a host of photo opportunities, with huge solar flares and sunspots sighted as activity ramps up.

Stars and Nebulae

To our eyes, the stars are points of light, but a telescope reveals many of them are embedded within dusty clouds of nebulae. It is only astrophotography that can truly pull out the fantastical colours and intricate structures of these faint objects.


No other celestial object showcases the vastness of the Universe as much as galaxies do. Collecting the light from these distant targets and then processing the captures to look their best is a real challenge, requiring great skill in astrophotography.

Young Astronomy Photographer of the Year

Many astrophotographers start the hobby at an early age, but that youth doesn’t mean their work is any less deserving. This special competition is open to any entrants under age 16, to showcase and encourage the great photographers of tomorrow.

Special Prize: Patrick Moore Prize for Best Newcomer

Don’t assume that you need high-end equipment and years of experience to get started in astrophotography. This special prize aims to encourage those who are new to the hobby and give their work a chance to shine.

Special Prize: Annie Maunder Prize for Image Innovation

The night sky should be open to all. This special prize asks entrants to process data from professional observatories in an innovative way – whether that’s creating false colour images, arranging it in a novel way, or creating a physical object using the data.
