Description

The Great Orion Nebula. My First LRGB image. I also added some Ha data on it, on Luminance (20%) and on the red channel (20%). Final image are made from 4 different exposure times so to be able to captured the huge dynamic range of the nebula. Exposure for 10 and 120 seconds for LRGB and 30, 120 & 300 seconds for Ha

Thanks for passing by
