Lagoon and Trifid Nebulae, Wide Field, 2019

At the end of the summer of 2019, I returned to my favorite dark sky in Greece to photograph two of the most spectacular nebulae of the entire night sky, the Lagoon (M8) and Trifid (M20) nebuale. To capture their brilliant colors I chose a very fast prime f/2 lens and a Hydrogen-α sensitive DSLR.
