Some of the vector illustrations I've made over the years (and continue to craft) for my introductory astronomy courses. Some are simple, some are not, and I merely peek over the ankles of giants. Sections are ordered like one might find in a typical textbook, and then mostly alphabetical order within a section. Click an image to get the vector graphics version, which you are free to modify.
