Got this just before clouds rolled in at midnight , took the pictures through multiple power lines so had to photoshop the diffraction pattern around alnitak. Total of 1hr 50min of 10 min exposures at iso 800 with canon 60D through SW ED120 with baader uhc_s filter , temperature 14-18 degrees. will try again when higher in the sky.
