OTOH it wouldn't be very interesting, unless there is a non-sync
interloper in the image, since they are virtually at the same distance.

have done some images of a NOSS trio, against the world map projection by
SkyMap, nicely showing the horizon, and the curvature of Earth's mapped
surface and the orbits.

That is also quite easy with graphical predictions. SkyMap produces highly
accurate HP-GL output, which can be rendered (and color-manipulated) with
