Astrotags are a new way to label your astronomy photos with their
celestial subject and its location. This short film, made by Jim Le
Fevre and Mike Paterson for the Royal Observatory's Astronomy
Photographer of the Year exhibition, shows you how.
So have a watch, then astrotag your pictures at the Astronomy Photographer of the Year group on Flickr. If everyone joins in we can make a beautiful and accurate map of the night sky... so pass the word on.
