FYI, just searched Google for "Tetuo Kudo," the Japanese amateur mentioned in this article and he uses 20 x 120 binoculars. Amazing to me that binoculars would play any role at all in modern astronomy, amateur or no.

They use binoculars due to their extreme wide field of view. For that specific application, hunting asteroids and comets, they are hard to beat. They can cover a lot more sky, much faster than astronomical telescopes that have much smaller field of views.

20 x 120 binoculars

These are kind of extreme for binoculars. Each lens is almost 5 inches in diameter. 20 power also means the field of view is somewhat limited compared to ordinary 7 or 10 power binoculars. Plenty of power and light-gathering ability; perfect for comet finding.
