Winner of the IAPY 2016 Stars and Nebulae category
The 2016 winner for the Stars and Nebulae category is 'The Rainbow Star' by Steve Brown (UK), taken at Stokesley, North Yorkshire, UK on 11 January 2016, using a Canon EOS 600D camera with Star Adventurer tracking mount, with 250 mm lens, at ISO 3200 with stacked 70 of 1500 frames.
What the photographer says
‘Whenever I see Sirius in the night sky I always take a moment to enjoy the rapid cycle of colours it displays, especially when close to the horizon. Sirius is called the ‘Rainbow Star’, as its twinkling seems to go through every colour of the rainbow. Ever since I took up astrophotography I have searched for the best way to show these colours in a photograph. After some experimentation, I finally hit upon the idea of videoing the star deliberately out of focus. To create the final picture, I picked out the video frames that contained the most striking colours and put them together in this composite image.’ Steve Brown
What the judges say
‘Such a simple and yet powerful idea with an execution that could well pass as pop art.’ Oana Sandu
