Astronomical cameras that use monochrome sensors with filters are not supported. Images must be RAW (from a supported camera), TIFF or JPEG. (Note that alt-azimuth mounts are not suitable for use with Starry Sky Stacker because the stars appear to rotate within the frame both during and between exposures). Starry Sky Stacker requires that an equatorial mount that ensures that stars move very little either during or between exposures is used during capture. The reduction in noise comes from combining a sequence of identical exposures into a single image.
Starry Sky Stacker is a Mac application that reduces noise in pictures of the night sky.
