The ST7 file type is associated with images captured by SBIG CCD cameras, specifically the ST-X series, which are designed for astronomical imaging. These files contain raw data from the camera's charge-coupled device (CCD), recording detailed information about celestial objects as seen through the telescope with which the camera is paired. The format is primarily used by astronomers and astrophotography enthusiasts for deep-sky imaging, allowing for post-processing to enhance detail, correct for atmospheric distortion, and calibrate colors. Given their specialized nature, ST7 files typically require specific software to open, analyze, and process the data they contain.
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.
