Instructions:

Help us find Kuiper Belt Objects! In these images they look like small white, well-defined blobs. Not all images will have them, but every one you find has a chance of being the final target of 'New Horizons'.

Step 1. Look for a nice blob of white in the messy residuals. This could be a Kuiper Belt Object! You may see black blobs. Don't mark those. Only mark white blobs. example
Step 2. Click the blob to place a circle around it. (If you click and drag inside the circle, you can move it around) example
Step 3. Repeat Steps 1 and 2 until you see no more solid white blobs.
Step 4. Want to mark asteroids or notate image quality? Read the tutorial to learn how!
Step 5. Click [Done Marking] when you're done. Nothing to mark? That's ok, you still click [Done Marking].
