At least twice, I have seen objects that appear one way with the naked eye, and quite another way through binoculars.
One event that I remember, and I've posted about on-line years ago:
I'm at my cousin-in-laws home. We're watching a slide show of a friends vacation. The cousins lived in the South Hills of Eugene, the house full of large picture windows. Great view. There we are, downstairs, and I'm looking at the little windows, just knowing that I will see a UFO that night. I just knew it.
Sure enough, I see a white light, orb shaped, come bouncing along towards us. I don't say anything. Wife to cousin-in-law finally says (I remember wondering when she would say something, for I was watching her watching it) "Are. you seeing this?" [paraphrase.]
We all look, and and watch, This round white bouncing light orb thing was certainly odd. No sound could be heard. And it didn't seem to behave anything like a plane, or helicopter. It was weird enough that we all ran upstairs.
Upstairs. Huge picture windows in the hills over looking the small city of Eugene, Oregon. We watch the light, still coming our way. Someone gets binoculars. We go out on the small catwalk like balcony to get a better look. The person with the vacation slides; he's upset. He's actually pissed. Angry. He says he doesn't want to look at it, and walks away. One could say he was merely offended that we ignored his vacation slides in order to chase this light, but I got the feeling -- as did others that night --that he was truly upset by the light. I seem to remember him saying something like "I don't need to know what that is."
Looking at the white orb like object with the binoculars, the object appeared to be very different. Suddenly it was a rapidly changing thing. It changed shapes, from square to orb to triangle to rectangle. And, it changed color. With the naked eye, it was white. But through the binoculars, the colors changed with the shapes; red, blue, green, yellow/golden, turquoise.
We continued to watch this as it moved towards us, then behind some trees, and then, gone.
I'm not saying it was the Space Brothers. It could have been a drone. This was back in the early 1990s. Not long after I saw my Orange Orb and, during the few years following, all kinds of weird events took place.
