Choosing Images to Process Discipline: Education Go to the archive search page where you can access thousands of astronomical files. Because this is for color imaging you may want to check the "Best observations" box under the Object Name box when you search so you will be more likely to get high quality images for processing. Some suggestions of images you might like to search the archive for are: M16 - the Eagle Nebula, M51 - the Whirlpool Galaxy, M57 - the Ring Nebula, M64 - the Blackeye Galaxy, NGC 5128 - "Centaurus A" Galaxy, NGC 5195 - Companion Galaxy of M51 Tags: archiveimage
