Another illusion I've noticed when viewing EGP through binoculars is that it
appears to make small "hops" to either side of it's mean path.   Presumably
this is some variant of the autokinetic illusion -- another I've seen when
watching naked-eye satellites  at high elevations is that they sometimes
appear to jump forward or back  a bit.
