183 individual frames make up this final image shot from my back yard observatory in Fremont MI, consisting of RGB, H-Alpha, OIII and SII filters for a Total Exposure time 17.8 hours.
The constellation of Orion is home to many treasures, including the Orion Nebula seen here. A small pat of the immense Orion Molecular Cloud, M42 is perhaps the most studied extra-solar object in the sky.
It is so very close to the Earth, only 1350 light-years, that this star forming region has opened the door to our understanding the processes that create stars and planetary systems. Only 24 light-years across, The Orion Nebula contains at least 2000 newborn stars with many still forming.
