What is SAOImage DS9?


SAOImageDS9


SAOImageDS9 is a super handy tool for anyone interested in astronomy! It's a multi-platform program built on Tk/Tcl that lets you visualize astronomical images and dive into complex FITS data with ease.



Open FITS Files Quickly


With SAOImageDS9, you can open new FITS files and start checking out the content in just a few minutes. This tool is not just limited to FITS, though! You can also import arrays, n-dimensional raster data (NRRD), flat-binary raster files (ENVI), and other formats like GIF, TIFF, JPEG, and PNG.



User-Friendly Viewing Panel


After uploading your images, you'll see the main viewing panel along with two smaller windows. These let you visualize space orientation on the map and zoom in on pixel-like objects for detailed inspection.



Adjust Your View


This tool makes it easy to adjust frames on the map, zoom in and out with preset levels, configure scales, focus on specific regions, or tweak parameters like masks, graphs, and crosshairs.



Customizable Interface


SAOImageDS9 is not only powerful but also offers solid performance with flexible design options. You can switch between light and dark themes depending on your preference. Plus, it has controls for all windows, plots, and dialogs!



Add Overlays for More Insights


The app lets you add overlays to any loaded image. These overlays provide useful configuration options for filtering and sorting your observations directly from the catalog dialog's config options. And if you're working with data from Chandra or Hubble Legacy Archive, the new footprint server boosts compatibility!



Analyzing FITS File Structures Made Easy


The built-in Prism feature helps you preview and analyze FITS file structures effortlessly. You can examine all extensions—including headers and table data—and even generate 2D plots and histograms straight from your column data.



A Great Choice for Astronomy Enthusiasts!


In summary, SAOImageDS9 is a fantastic option for anyone looking to do deep analysis in astronomy. Best of all? It’s free! There's plenty of documentation available to help you get started learning too. Plus, it's supported by a vibrant astronomical community ready to lend a hand whenever needed.
