Description

A six and a half hour integration of Crescent Nebula and the surrounding background nebulosity. Imaged with an UNMODIFIED Canon 5D III on a Canon EF 600mm f/4 L II lens and EF 1.4x TC III (840mm). Due to persistent weather, and a few technical problems on some nights, it took a little over a month to gather enough subs to pull out the background nebulosity this birghtly.
