This is my attempt at processing the previously available IC434 data. I used Astro Pixel Processor and created a synthetic luminance from the RGB data (details on the APP tutorial page), so the result is HaLRGB. Taming Alnitak is beyond my current processing skills (I suppose I will have to learn about masks) but I am happy enough with the result - orange Flame Nebula, yellow stars, faint stuff and red Ha region.
