I'd like to know how they stabilized the scope and the subject so that the two either don't move or move in unison. At this scale, somebody slamming a door in the next state would cause it to wobble noticably.
Give it a lot of intertial mass and separate it from everything around it with very low pass shock absorbers.
Lots of existing scientific instrumentation works this way.
Of course, its typically expensive as heck, since you need to build a special floor just for the instrument.
