Before you watch the video clip I am going to warn you to never look directly at the Sun - even a couple of seconds is dangerous and could cause long-term damage to your eyes and telescope. I do not want you to go blind, so do not look at the Sun.

Remember that although it takes about 30 seconds for the really obvious damage to happen to the grape, your retina will suffer in an extremely short amount of time. Do not think you will be safe if you just take a 'quick look'.

Now that you've had that warning, you can proceed to the video clip.
