An amazing astrophotographer has captured the International Space Station in transit as it passes in front of the sun.
Mehmet Ergüney, from Bad Kreuznach, Germany, captured the sequence – which involves being at the right place, at the right time, with the right weather.
Mehmet, from Turkey, said: “At this time, the Space X Dragon Crew capsule was docked at the ISS.
“In this one second my adrenaline is at an all time high, and it’s addicting. A small mistake like a missing cable, too little battery or weather could all kill my photo.
“This event happens only a couple of times a year. You always must be there at the right time, in the right place and with the right equipment and weather.
“My photo has become very popular online and I’ve received lots of congratulations from astronomy fans all over the world.
“I put a lot of time, money and energy into my photos, many think I am crazy. But when I see the results, I am always fascinated myself.
“Taking photos shows me how small and insignificant we are in the universe.”
