Highly commended for the IAPY 2016 Galaxies category
The 2016 highly commended image for the Galaxies category is 'Antlia Galaxy Cluster: Extreme Deep Field' by Rolf Wahl Olsen (Denmark), taken at Auckland, New Zealand on 1 July 2015 using a home-made 12.5-inch f/4 Serrurier Truss Newtonian telescope with Losmandy G11 mount and QSI 683wsg-8 camera, with multiple channels and a 152-hour total exposure.
What the photographer says
‘Over the course of six months, I used a home-built telescope to collect 152 hours of exposure of this magnificent and rarely imaged galaxy cluster. Scattered across the background are a vast number of deep red galaxies, many of which appear grouped into distant clusters of their own. This could be the deepest view ever obtained of the Antlia Galaxy Cluster, and likely to be the longest exposure reached by an amateur.’ Rolf Wahl Olsen
What the judges say
‘I can spend hours gazing into this picture. It’s incredible that in this small patch of sky there must be close to one hundred galaxies, each containing billions of stars, and all captured from the surface of this small rocky planet by the dedication of one amateur astronomer!’ Chris Bramley
