DeepSkyStacker (DSS) is a user-friendly tool for stacking astronomical data, supporting various RAW file types. This tutorial guides users through familiarizing with DSS’s interface, registering and stacking images, and handling both DSLR/color and monochromatic data. Steps include setting master frames, choosing stacking options, saving stacked images, and preparing data for post-processing edits. It emphasizes using the Kappa-Sigma clipping mode for processing over five frames and recommends saving TIFF files. Monochrome data requires stacking filter sets separately before editing.
