The image size of this camera is unbelievably huge in its coverage.

Most telescopes take pictures of objects - this one takes pictures of the entire sky. And will do so in a time-lapse fashion for 10 years.

It's simultaneously more in line with a human's experience than an obscure wavelength of tiny object not visible to the naked eye - it takes a high-resolution picture that's similar to what you'd see if you look at the sky. But it's also profoundly grand beyond a human's experience because of just how much stuff is collected.
