Description
The ST4 file type is associated with the SBIG CCD camera ST-4, a device primarily used in astrophotography. This file format is designed to store images captured by the SBIG ST-4 camera, which include data crucial for astronomical observations such as star fields or celestial events. The ST4 format contains both the image data and metadata regarding the capture settings, providing astronomers and enthusiasts with the necessary information for analysis and processing. It is specifically tailored for the astrophotography community, allowing for detailed examination and manipulation of astronomical images.
An ICO file is an image format used to store icons for Windows programs, files, and folders. It contains two bitmaps: 1) the AND bitmap - the image mask (which determines what part of the icon is transparent) and 2) the XOR bitmap - contains the icon which is mapped onto the image mask. ICO files can be modified to create custom icons.
