Permission for nonprofit, non-commercial organizations (clubs, schools, universities, etc.) is usually granted for free if appropriate credits are given to the author, but you will have to ask. If desired, I can supply files of higher resolution.

Commercial and for-profit users should contact Walter with a description of their intended use. Please understand that we cannot give away our images for free as these are professional images taken with expensive professional equipment, and long cold hours at the telescope and nearly as much time before the computer screen went into the creation of these images.
