Processing technique
Astronomical Image Processing
The steps that turn calibrated, stacked exposures into a finished image — stretching the very high dynamic range so faint nebulosity and bright cores both show, balancing colour, reducing noise, and sharpening detail. Done honestly it reveals what the data contain; the goal is to represent real signal, not to invent it.
