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.

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

Stacking solves this by mathematically combining many short exposures (called "subs" or "light frames"). This process improves the . While the signal (the nebula) stays in the same place across frames, the noise is random and "averages out" during the stacking process. Key Concepts and Frame Types

Using DSS is generally a straightforward "top-to-bottom" process within the software's sidebar: deepskystacker

The star detection threshold in DSS is often set too high by default. If DSS is not detecting enough stars (or if you have a very noisy image), go into the Register Settings and lower the "Star Detection Threshold" slider to ensure it finds enough reference points to align the image.

: Images of a uniform light source (like a white t-shirt over the lens at dawn). These correct for vignetting and dust spots on your sensor.

However, if you need a for referencing DSS in a paper or report, here are the standard ways: To clarify: by its author, Luc Coiffier

One fateful evening, Emma decided to test DeepSkyStacker on a particularly tricky target: a distant, faint nebula in the constellation of Cygnus. She had been trying to capture it for years, but the images always seemed to be plagued by noise and distortion.

When you photograph distant galaxies or nebulae, the light hitting your sensor is incredibly faint. To see detail, you need long exposures, but long exposures introduce significant and electronic interference.

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). Stacking solves this by mathematically combining many short

: Fast exposures (highest shutter speed) with the lens cap on. These remove the electronic "read noise" inherent to your camera's sensor. How to Use DeepSkyStacker: A Step-by-Step Workflow

DSS simplifies the technical workflow of astrophotography by automatically handling the three types of calibration frames:
