The ST6 file type is associated with the SBIG CCD camera ST-X series, which are specialized cameras used in astronomy for capturing images of celestial objects. These files contain raw image data captured by the camera's charge-coupled device (CCD), allowing astronomers and astrophotographers to process and analyze the images with high precision. The ST6 format is designed to preserve the original quality and detail of astronomical observations, making it crucial for research and detailed study of the night sky. It typically requires specific software to open and process the data for further use in astronomical analysis and imaging.
A WEBP file is an image saved in the WebP (pronounced "Weppy") raster image format developed by Google for web graphics. It is designed to reduce image file sizes over standard JPEG compression while maintaining the same or similar quality. WEBP files allow images to be downloaded more quickly.
