Description

Another narrowband image in which I opted to "go full gas" when processing (to borrow from cycling vernacular). The basic combined SHO image is stretched using the STF transferred to the Histogram Transformation tool and is not a process I recommend in any other processing workflow but does help with faint detail. When a synthetic luminance from the Ha, or a combination of the three channels, is applied via CieLab combination the base SHO initial image image is tamed somewhat. The image isn't terribly "real" in any sense but is a style that does serve to illustrate the nebulous structure. It most certainly is not to everyone's taste, I do appreciate.
