What is the difference between .st4 and .png?

Description: The ST4 file type is associated with the SBIG CCD camera ST-4, a device primarily used in astrophotography. This file format is designed to store images captured by the SBIG ST-4 camera, which include data crucial for astronomical observations such as star fields or celestial events. The ST4 format contains both the image data and metadata regarding the capture settings, providing astronomers and enthusiasts with the necessary information for analysis and processing. It is specifically tailored for the astrophotography community, allowing for detailed examination and manipulation of astronomical images.; A PNG file is an image file stored in the Portable Network Graphic (PNG) format. It contains a bitmap of indexed colors and uses lossless compression, similar to a .GIF file but without copyright limitations. PNG files are commonly used to store graphics for web images.
