Rosette Nebula in Monoceros. Stack of two 15-minute exposures at f6 with 5-inch apo refractor (no field flattener) and Canon 20Da camera. ISO 400, with in-camera noise reduction and temperature about 0 C. Some light haze. Taken January 4, 2006. Two other exposures taken in the series were hazed out completely as cloud moved through. Image cropped slightly due to re-polar alignment between shots to cut down dec drift which caused misregistration of frames. Levels and Broad USM applied to L layer after converting to Lab mode to darken dark fingers of dust.
