This is just a note to stress the importance of generating valid metadata in acquired images. This is astronomy, and we are acquiring astronomical observations, not casual daylight pictures. Without a minimum of valid metadata, an astronomical image has essentially no documentary value, and its possibilities for further analysis are essentially nullified.
Metadata for the time of observation, approximate image scale, and approximate location in the sky are the absolutely essential minimum; without them, you are not doing astronomy but just gathering a nonsensical array of numbers.
