This year’s Insight Astronomy Photographer of the Year competition received a record 2700 entries by astrophotographers from 59 countries around the world. These astonishing pictures reveal fresh perspectives on astrophotography favourites alongside some of the great astronomical events of the last year.
We will showcase the winning images from all 11 categories over the next few days, but if you wish to see them all together on display, the Royal Observatory Greenwich has an exhibition open 18 September 2015 — 26 June 2016. Hours: 10.00–17.00, entry is free.
Steve Ringwood investigates a new range of neutral white solar filters employing Baader Planetarium’s renowned Astrosolar safety film in a robust, temperature-compensated frame and easy-fitting mount that comes in a range of apertures from 80mm to 280mm diameter.

Some 4 billion years ago, the Sun shone with only about three-quarters the brightness we see today, but its surface roiled with giant eruptions spewing enormous amounts of radiation into space. These powerful solar explosions may have provided the crucial energy needed to create greenhouse gas in Earth’s atmosphere, warming the planet and incubating life.
