Open FITS Files

FITS (short for Flexible Image Transport System) is an image format widely used for storing grabbed frames from telescope observations.

Particularly developed to save and store astronomical image data in a standard format, the FITS format usually contains both ASCII text and binary data.

In order to view their FITS images, users will have to find and use a specialized graphic app that comes with built-in support for this specific image format.

FITS viewers will also allow their users to export their images to other graphic formats that can be accessed and edited with a wider range of apps.
