Description

After 4 nights battling 40'C heat and haze during the day, pretty happy overall how this turned out. Attempted a 'HDR' on Orion but I suspect I may need some shorter subs to expose the core without blowing out. Anyway here's my take on M42, NGC1975, IC434 and NGC2023 in HSO (RGB combine). Total of 9.5hrs integrated in APP and tweaked in PS. Clear Skies !
