DeepSkyStacker is a free astrophotography software that allows you to process deep-sky images. It enables stacking multiple astronomical photos (light frames, darks, flats, and bias) to improve the final quality, reducing noise and enhancing details of objects such as galaxies, nebulae, and star clusters.
Through a simple interface, it supports automatic alignment, calibration, and combination of images in formats such as RAW, FITS, and JPEG.
It is compatible with Windows and offers tools for post-processing adjustments, making it a popular choice among amateur astrophotographers seeking professional results.
