Galileo wasn’t just an astronomer—he was a rebel. The guy looked up, saw Jupiter’s moons, and basically told the Pope, “Hey, maybe Earth isn’t the center of the universe?” That earned him a trial, house arrest, and legendary status as the original troublemaker of science.

So, let’s honor Galileo in the way he’d appreciate—by defying the ordinary.

For one week only, we're giving 5% off all regular-priced items with a discount code that pays tribute to his rebellious spirit:

🚀 Code: EPPURSI

(As in Eppur si muove—"And yet it moves," the famous phrase Galileo supposedly muttered after being forced to recant his heliocentric claims. A perfect nod to questioning authority and trusting what you observe.)

Want a new eyepiece? A telescope? A mount that actually moves with the sky? Use the code EPPURSI at checkout and save 5%.

Offer ends Sunday, February 25th at midnight—don’t let the Inquisition or time catch you off guard. 🚀
