How to Make a Homemade Solar Observatory for Viewing Solar Eclipses

TLDRLearn how to create your own homemade solar observatory using simple household items to safely view solar eclipses

Key insights

🔭Create a makeshift solar observatory using a camera obscura and a cardboard roll

🌞Ensure safety by avoiding direct viewing of the Sun without solar glasses or proper equipment

🌍Align the cardboard roll and lid to find the Sun's position and create a projection of the Sun's image

🎨Customize the solar observatory by painting the edges and adding a dark cardboard disc for better image quality

📷Observe the Sun's image on the screen, which may appear upside down, due to the camera obscura effect

Q&A

Is it safe to look directly at the Sun during a solar eclipse?

No, it is extremely dangerous to look directly at the Sun during a solar eclipse without proper safety measures such as solar glasses or a solar observatory.

Can I use any type of cardboard roll?

Yes, as long as it is sturdy and can hold its shape. A toilet paper roll or paper towel roll can be used.

Do I need to drill a hole in the cardboard roll?

Yes, a small hole is necessary to allow the sunlight to enter the observatory and create an image on the screen.

Is it necessary to paint the edges of the solar observatory?

Painting the edges helps to reduce ambient light reflections and provides a cleaner, more professional appearance.

Why is the Sun's image upside down on the screen?

The camera obscura effect causes the image to appear upside down. This is a natural phenomenon and is not specific to this homemade solar observatory.
