Different processing on Orion Nebula

This new processing of Messier 42 made with the HORUS setup is showing more extensions of the Orion Nebula, far away from its core, in the deep H-alpha light with a CHROMA narrowband filter.

A total of 21.5 hours of exposure time was necessary to reveal those faint details.
