The Insight Astronomy Photographer of the Year 2018 competition is now open for entries, meaning its time to select and enter your best astrophotos for a chance of taking the top spot and winning the grand prize of £10,000.
This year, the competition is celebrating its tenth anniversary by hosting an exhibition of the winning images in a new dedicated gallery space at the National Maritime Museum, Greenwich.
The exhibition, opening 23 October 2018, will feature 100 incredible astro images from the competition’s history, including this year’s winning entries.
Entrants now have until Friday 9 March to enter up to ten images into any of the nine categories and two special prizes.
As well as the £10,000 grand prize, there are prizes of £1,500 for the winners of each category, £500 for runners up and £250 for highly commended images.
Winners of the special prizes will each receive £750.
Insight Astronomy Photographer of the Year 2018 is run by the Royal Observatory Greenwich in association with Insight Investment and BBC Sky at Night Magazine.
The competition has nine main categories: Skyscapes; Aurorae; People and Space; Our Sun; Our Moon; Planets, Comets and Asteroids; Stars and Nebulae; Galaxies and, for those under 16 years old, the Young Astronomy Photographer of the Year.
There are also two special prizes, The Sir Patrick Moore Prize for Best Newcomer and Robotic Scope, the latter of which recognises astrophotos taken using one of the many telescopes around the world that can be controlled by members of the public via the internet.
If you need some inspiration before entering this year’s competition, you can see the winning images of 2017 in a free exhibition at the Royal Observatory, open until 22 July 2018.
