Most Get This Wrong… Why Size Matters (But Not How You Think!)

What if I told you that a tiny telescope could produce a larger Moon image than a much bigger one? Sounds impossible, right? Most people get this wrong—but the answer might surprise you.

In this video, we’ll test three different telescopes in a game to see if you can guess which one took each Moon image. Then, I’ll break down why Field of View (FoV) isn’t just about focal length—and how sensor size plays a crucial role.

Stay until the end for an insanely detailed, high-resolution Moon image that took me thousands of frames to create.
