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.
WebP Image (WEP) is an image file format developed by Google in 2010. It is based on the VP8 video format and is used to create smaller, higher quality, and lossy compressed images. It is supported by most major web browsers and is commonly used for web graphics.
