Fast local CLI that grades astrophotography subframes (FITS, fpack .fz, XISF, TIFF, camera RAW): stars, FWHM, HFD, eccentricity, SNR, PixInsight PSF SNR/PSFSW/SNRW weights, sky brightness, satellite trails. Flags outliers, checks calibration frames, maps tilt and recommends drizzle and WBPP settings.
