The HST Dither Handbook describes strategies for obtaining dithered observations using the instruments aboard the Hubble Space Telescope. Techniques for processing and combining these observations using the "Drizzle" software are also described, including details on how to align the images and perform cosmic ray rejection, before combining them into a single final image.
