Starry Sky Stacker
macOS / Photo et vidéo
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. Neither alt-azimuth mounts nor cameras that generate FITS files are supported. A free trial version is available at the developer's website.
Quoi de neuf dans la dernière version ?
Replaced the median composition algorithms with variations on truncated mean that should result in slightly better results.
Added support for 32-bit floating point output. This should improve image quality when there are a large number of input images and the noise in the input images is small. 32-bit output is off by default. It can be turned on in settings. See details online before turning it on--32-bit float data is not well supported in many image editing apps.
Added support for lens distortion correction when processing RAW images. Lens distortion correction is off by default. See details online before turning it on.
Bug fixes and significant internal changes to facilitate future upgrades. See full details at https://sites.google.com/site/starryskystacker/new-in-version-1-5
