Crescent Nebula

André van der Hoeven, Hendrik-IdoAmbacht, Netherlands, 2016–19

André says: “I like this image because of the beautiful Crescent Nebula, but even more because of the ‘hidden’ Soap Bubble – a very faint nebula like a cosmic pebble hidden in plain sight. It’s amazing this was only discovered in 2008 and how it’s now possible to image it with equipment that is in reach of the average astrophotographer.”
