There are just over two weeks left to enter the Insight Astronomy Photographer of the Year 2017 competition run by the Royal Observatory Greenwich in association with Insight Investment and BBC Sky at Night Magazine. Entries must be submitted by noon UK time on 7 April.

Each entrant can submit up to 10 images to the competition. You don't have to be an expert or have fancy equipment to be in with a chance of winning a prize. The competition has nine main categories, including Skyscapes (astronomical subjects such as the Milky Way or stars alongside earthly scenery), People and Space (photographs of the night sky with people or a human interest element) and Young Astronomy Photographer of the Year (for entrants under 16 years old).

Photographers can enter their images online by visiting, where full competition rules and some top tips on photographing everything from star trails to galaxies and nebulae are also available. To inspire you, IBTimes UK presents some of this year's entries so far.
