Observatory (com.codeobsession.observatory) is a Mac OS X software application that has been discovered and submitted by users of iBoostUp.

The latest version that our iBoostUp users have reported seeing on their systems is Observatory 41. The most popular version of this application used by our users is version 44. Observatory requires macOS 10.11 or later.

Publisher Description:
Collect and curate your astronomical images. Search 10+ professional image archives simultaneously. Create master bias, dark and flat frames. Calibrate, register, stack and adjust your FITS, XISF (PixInsight), SBIG and RAW images, all nondestructively.


  • Quick Look & Spotlight: display thumbnails, previews and metadata of FITS, XISF and SBIG images in Finder and other applications. Observatory also helps your Mac index the metadata, so you can quickly find your images by dimensions, exposure time, focal length, detector temperature, right ascension, declination and more.

  • Discover whats in your images by overlaying millions of stars, galaxies, planetary nebulae, confirmed exoplanets and other objects of the Messier, NGC/IC, Tycho-2, CGPN 2000, GCVS 5.1, WDS and PGC 2003 catalogs, or use the UCAC4 and USNO-A2.0 catalogs for an additional 500 million stars.

  • A flexible hierarchy: create as many libraries as you wish and keep your images organized with albums, smart albums and folders. Let Observatory keep track of your images, without copying, moving or altering them.

  • Observatory automatically normalizes the image metadata in its libraries, categorizes images, and supports metadata bulk editing. You can also manually tag, rate, color code, reject or archive images. And you can add notes or attach important reference material to your images and albums.

  • A nondestructive preprocessing workflow without the hassle of intermediate files.

  • Plate Solving: if some of your images lack the information to relate image pixels to actual sky coordinates, Observatorys plate solver will help you find the best match.

  • Measure: image statistics, aperture photometry, PSF fitting and astrometry.

  • Open FITS, XISF and SBIG images at full bit depth in Acorn, with help of our Acorn plugin.
