The transit of Venus across the sun on June 5, 2012. A very rare event.
How to look at the sun without going blind?
The paper plate and T-shirt on the telescope created shadows on the poster board, so only the sun was projected. The barn doors were almost closed to create enough darkness. “Never look directly at the sun with a telescope”….DUH!…But you can make an impressive image by projecting on a screen with a telescope or binoculars.
