3-Hole PUNCH Pinhole Projector
Thank you for your curiosity about why we see round images of the Sun through non-round holes!
The PUNCH Outreach team created the 3-Hole PUNCH Pinhole Projector to help explore how and why pinhole projection works to create real images of the Sun.
Please give us your feedback on our prototype projector and/or this explanatory presentation.
