Astronomy Photographer of the Year judges explain how to get involved in astrophotography

A stunning juxtaposition of an ethereal solar system body, long-period comet C/2014 E2 Jacques, and the vast, heart-shaped emission nebula IC 1805, some 7,500 light-years away in the constellation Cassiopeia — winning image of the Planets, Comets & Asteroids category in the Insight Astronomy Photographer of the Year competition 2015.

In this video, the judges of the Insight Astronomy Photographer of the Year competition explain what makes the perfect astrophoto. The winning image will be revealed at an awards ceremony on 15 September.

The rusty red swirls of the circular, iron sculpture Seven Magic Points in Brattebergan, Norway mirror the rippling aurora above.
