Starry Sky Stacker reduces noise in pictures of the night sky that are captured as a sequence of exposures taken with a modern dSLR or mirrorless camera using an equatorial mount. Starry Sky Stacker aligns the images to compensate for errors in tracking, assigns a quality estimate to each image, allows the user to select images based on the quality estimate, and composites the remaining images. The resulting image has much less noise than any of the original images.
Is an image procesing program that is oriented primarily toward astrophotography
