Unusual sightings and mysteries spotted through a telescope

lately i've been seeing this weird glint drifting across the edge of my field of view whenever i'm out late with the scope. not a satellite (at least not like the usual ones), more like a tiny flicker that hangs for a second, then slides off like it got spooked. last night it actually doubled back, which kinda made my stomach drop because nothing up there should *do* that.

could be i'm just tired and my eyes are doing their own thing, but it reminded me of when i was a kid staring at the lake at dusk, swearing i saw something move under the surface. anyone else ever catch something through the scope that made you do a double take?
