The August 21, 2017 eclipse will be observable across America. While those in the path of totality will see a TOTAL solar eclipse, everyone will be treated to a PARTIAL eclipse. To help you celebrate this rare event, NASA released STL files for a 3D Printed Pinhole Projector in the shape of the USA and/or a US State.
You can also capture the moment: Ask a friend to take a picture of your shadow while holding your state’s pinhole projector. The resulting image will be a once in a lifetime picture of your shadow, the shadow of your selected state and a projected image of the partial eclipse marking your location!
And you can of course share the moment: by sharing your best images with us on Instagram, Facebook, Twitter and/or on NASA’s Solar Eclipse Flickr Group. Use #EclipseSelfie as a tag and leave a 1-2 sentence description of your image/idea.
3D Printed Pinhole Projection Cards
During the 2016 total solar eclipse in Micronesia, NASA engineers tested a variety of pinhole sizes using 3D printed cards . They found that a 5 mm pinhole held 3-4 feet above the ground provided the strongest and clearest pinhole projection of a partial eclipse.
Be creative but be safe! NEVER look directly at the sun or through optical devices such as pinhole projectors, binoculars or telescopes! Check out these Eclipse Viewing Safety and Related Projection Methods.
