Description
The ST5 file type is specifically associated with images captured using SBIG CCD cameras, particularly the ST-X series models. These files contain raw, unprocessed image data directly from the camera's charge-coupled device (CCD), which is sensitive to light. The format is designed to preserve the maximum amount of image information, allowing astronomers and astrophotographers to perform detailed post-processing. The ST5 format is commonly used in astrophotography and astronomical research, where high precision and image fidelity are crucial.
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.
