I'm an ESO photo ambassador, using my handy access to ESO observatories to create nice images. All of my ESO-related photos are freely available from the ESO image archive, and several timelapses are in the ESO video archive. They are free to use as you like, the only condition being that you must clearly credit them. There's no requirement to tell me if you use my images, but I always appreciate knowing! If you like these photos, you may also like my work on 500px, flickr and youtube.
