This image of the Elephant Trunk nebula is the result of about 11 hours of exposure over 3 nights. The nebula is an area of gas and dust located in the constellation Cepheus. It's about 2,400 light years away. Which means that the photons I captured last month on my deck left the region around 419 BC, right about the time that Plato was born in ancient Greece.
