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
You can search either by name or by number. For example you might search for, "M57" or "Blackeye Galaxy" or "NGC 5195."
Choose an image that has at least red, green and blue FITS files and download the files to your computer.
