Deepskystacker [work] Here

However, if you need a for referencing DSS in a paper or report, here are the standard ways: Software reference: Coiffier, L. (Year of version used). DeepSkyStacker (Version X.X.X) [Computer software]. Available at: http://deepskystacker.free.fr Alternate citation (if mentioning the algorithm): DeepSkyStacker implements standard stacking methods: median, average, sigma-clipping, and entropy-based alignment. No original paper; refer to general image stacking literature (e.g., M. T. B. South, “Astronomical Image Stacking,” 2010). If you meant you want a paper on deep-sky image stacking techniques (not DSS specifically), I can provide references for the algorithms DSS uses (e.g., sigma rejection, registration). Let me know.

To clarify: by its author, Luc Coiffier. DeepSkyStacker was released as free/open-source software for the amateur astrophotography community, not as part of a traditional academic publication. deepskystacker

I think you may be referring to — a popular freeware tool for astrophotography image stacking — and asking for a scientific paper that describes it. However, if you need a for referencing DSS
