Exposures: 15 x1 20s red green and blue, 10 x 300s H-alpha using my Starlight Xpress H694 camera and Starwave 70mm on the Cem60ec. Stacked and processed in Pixinsight. I combined the Ha with the red channel using a NBRGB script and then used a luminance channel extracted from the HaRGB image which was sharpened using HDR to reduce the brightness of the Trapezium area, then recombined. Some noise reduction and gentle curves manipulation to finish.
