What's in the Garbage Can?

Why is everyone looking into and photographing the garbage can?  Clues can be found in the device on the stand to the left, and the bright thing on the stand in the far distance.  What we are looking at is a solar telescope.  The thing on the stand is a mirror which captures the sun, and reflects it onto another mirror way in the distance, and that mirror projects the image of the sun into a white card inside the garbage can.  You need the garbage can as a shield to keep stray sunlight off the sun,s image.  Everyone was amazed at the sun's image, including a sunspot or two, and everyone wanted to take a picture of the sun.
