It is built for the shots that come off smart telescopes, backyard rigs, and late-night moon sessions: the ones that are almost there, but need a cleaner sky and a better finish. Start fast with Auto Astro Polish, Deep Sky, Moon Sharp, and other built-in looks. Or dial it in by hand with controls made for space photos, including black point, glow cleanup, nebula reveal, galaxy detail, denoise, star reduction, and moon sharpening. Import from Photos or Files, work with JPEG, PNG, HEIC, TIFF, RAW-style images, and FITS sessions, then export finished images or shareable before/after cards. Batch Finish helps run one look across a queue when you came home with more than one keeper. AstroFinish stays local. No account. No cloud upload. No tracking SDKs.
