"I started taking this photo from Spain in 2011, and after shooting the main central part of the Orion Nebula, I wanted to try and capture the four Corner Stars and go deep in search of all the dust in-between those markers. In 2014 I teamed up with Olly Penrice to help me finish this project in RGB and H-alpha. In total we ended up with 34 panes totalling over 400 hours of exposures. Calibration of the data was done by myself and Olly."
