Observatory is an image management application specifically designed for astronomy. It helps you keep your astronomical images organized with albums, smart albums, tags, ratings and color labels. You can use Observatory to create master bias, dark and flat frames, calibrate, register, stack and adjust your images, all nondestructively. Add notes, plate solve, have it automatically tag your images, and overlay astronomical catalogs. Observatory even lets you search and download research images directly from 10+ professional image archives.

With Observatory, your Mac also gains the ability to display thumbnails and previews of astronomical images in Finder and other applications. And it helps Spotlight index the right metadata, so you can quickly find your images.
