Dumbbell Nebula (M27)
Photo description / processing
My first experience shooting a deep space object through narrowband filters. The shooting was done at a sensor temperature of 0°C. The color was formed according to the HOO (bicolor) scheme, added on top of the luminance channel (shot through a UV/IR cut filter). Unfortunately, the OIII filter produced large halos around the stars.
