<commit_before># OpenSkyStacker

Multi-platform stacker for deep-sky astrophotography.

[![Build Status](https://travis-ci.org/BenJuan26/OpenSkyStacker.svg?branch=master)](https://travis-ci.org/BenJuan26/OpenSkyStacker) [![Documentation](https://codedocs.xyz/BenJuan26/OpenSkyStacker.svg)](https://codedocs.xyz/BenJuan26/OpenSkyStacker/) [![Coverage Status](https://coveralls.io/repos/github/BenJuan26/OpenSkyStacker/badge.svg)](https://coveralls.io/github/BenJuan26/OpenSkyStacker)

OpenSkyStacker assists in the processing of deep-sky images. *Stacking* in this context means taking the average of several exposures of the same object to reduce the noise and boost the signal-to-noise ratio. This is especially helpful in the field of astrophotography because many objects of interest are so dim that, without processing, they might be indistinguishable from noise.

OpenSkyStacker is not unique in what it accomplishes, as there is other stacking software out there, but it is unique in that it is free, open-source, and available for nearly any operating system.
