Rosette Nebula

Tried a stab at the Rosette from an orange zone using only a Hoya Red Intensifier Filter (Didymium) and an unmodified Olympus EM5 with fourteen 221sec exposures at ISO800 and 12 darks. AT115EDT with matching 0.8x FR/FF. Outer edges cropped to remove stacking artifacts. Stacked in DSS, Initial stretch and separation into R/G/B files via Fits Liberator, remaining processing done in Perfect Photosuite 9.5, PS CS4, and LR 5.6
