Description

The Great Orion Nebula (M42) in HaRGB - Two cameras were used with the RASA 8. The RGB image was creating from a HDR composition of three separate stacks of 10s, 20s and 30s exposures with the ASI294MC Pro & Optolong L-Pro filter. The red channel was enhansed using HA data captured with the ASI1600MM Pro & Baader high speed Ha filter. The combined image was then boosted using a synthetic luminance channel created by combining the luminance of the RGB image with the HA data.
