Observatory

Your image library for astronomical research

Introducing Observatory

Observatory is a full-featured and beautifully designed Mac application that makes collecting and curating astronomical images delightful. Whether you are a professional astronomer, an advanced amateur or a student, Observatory helps you discover, organize, process and analyze the astronomical images for your research.

Organize

Create a library for each of your research projects 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.

Virtual Observatory

Search 10+ professional archives simultaneously and download research images from

European Southern Observatory
W. M. Keck Observatory
Gemini Observatory
Hubble Space Telescope
Spitzer Space Telescope
WISE Space Telescope
Palomar Transient Factory
Two Micron All Sky Survey
Sloan Digital Sky Survey
Digitized Sky Survey

Conveniently access the research images of the Hubble, Spitzer and WISE space telescopes, 10 m W. M. Keck Observatory telescopes in Hawaii, 8.2 m VLT telescopes in Chile, 8.2 m Gemini North and South telescopes, 3.6 m New Technology Telescope, 2.6 m VLT Survey Telescope, 4.1 m VISTA, and many more.

Find & Import

To help you decide which images to download, Observatory provides quick access to image previews, and allows you to filter results.

Calibrate, Stack & Process

Manually stack images to obtain the best signal to noise ratio, or let Observatory autostack for you. It can even assign a weight to each image in the stack, based on various criteria.

Create master bias, dark and flat frames. Calibrate, normalize, align, stack and adjust your FITS, XISF, SBIG and RAW images, all nondestructively.

Calibrate, Stack & Process

Analyze & Discover

Image statistics, aperture photometry, PSF fitting and astrometry. Observatory also lets you compare images side-by-side or blink them.

Analyze & Discover

Share & Export

With its advanced export preset support, you can easily convert your images to FITS, SBIG, TIFF, JPEG and PNG file formats, optionally resizing them, and use folder & file naming templates to conveniently export them any way you want.

Export Preferences

Quick Look & Spotlight

Observatory provides Spotlight and Quick Look plugins for FITS, XISF (PixInsight) and SBIG images.

You can preview them directly in the Finder and have it display useful information like image dimensions, exposure time, focal length, detector temperature, right ascension and declination. With Observatory, you can also search for this information right from within the Finder itself.

Observatory even includes FITS, XISF and SBIG plugins for Acorn, so you can open these images directly in this powerful image editor for post-processing.

Overlays

Overlays

Overlay the 3.5 million stars, galaxies and other objects of the Messier, NGC/IC, Tycho-2 and PGC 2003 catalogs on your images.

External Catalogs

External Catalogs

In addition to the built-in catalogs, Observatory also supports the UCAC4 catalog with over 100 million stars and the USNO-A2.0 catalog with over 500 million stars.

Astrometric Matching

Astrometric Matching

If some of your images lack the information to relate image pixels to actual sky coordinates, Observatory’s plate solver will help you find the best match, using its built-in catalogs, as well as the UCAC4 and USNO-A2.0 catalogs, and with help of the SIMBAD and NED services.

Multiple Libraries

Multiple Libraries

Observatory is not limited to a single library. You can create a library for each of your research projects, and have multiple libraries open at the same time. And they are all integrated with Time Machine.

Notes & Attachments

Notes & Attachments

Your albums and even your individual images all may have notes and files attached to them. So while you analyze your images, you can have quick access to relevant research papers and jot down notes in each image.

FITS Headers

FITS Headers

Observatory automatically normalizes the image metadata in its libraries, but you still can view and even search within the original master FITS header.

Quick Search

Without creating Smart Albums, Observatory will let you search images by type, name, tag, filter and status. Similarly, you can quickly search your collections by name, tag and status.

Quick Search

Versions

You can create as many versions as you wish of an image and process each in a different way, without ever modifying the master image.
