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.
Based on HEVC (High-Efficiency Video Coding), the HEIF format is an image file container with one or multiple images and is the default image format for Apple Live Photos. It replaced the JPEG format as it's smaller in size and has lossless compression ensuring high-quality photos.
