The Royal Observatory Greenwich is hosting the 2015 Astronomy Photographer of the Year in association with Insight Investment and BBC Sky at Night Magazine.
The overall winner of the 2015 competition will receive £2,500 and prizes will be awarded to the winners of each of the competition categories.
There are also two special prizes: The Sir Patrick Moore Prize for Best Newcomer is awarded to the best photo by an amateur astrophotographer who has taken up the hobby in the last year and who has not entered an image into the competition before, and Robotic Scope, acknowledges the best photo taken using one of the increasing number of computer-controlled telescopes at prime observing sites around the world which can be accessed over the internet by members of the public.
The winning photographs will be exhibited in the Astronomy Centre from 18 September 2015.
