Re: from little plot seeds, mighty games do grow: Share you ideas!
[True background information: Modern large ground-based astronomical telescopes usually have two of what are called "Naismith platforms". The telescope has an alt-az mount (a pivot that tips the 'scope up and down is the altitude axis; then that structure is on a turntable that is the azimuth axis), and a flippable mirror in the center of the 'scope diverts the light through either of the two altitude bearings, which are open rings with smaller bearings on the ring surfaces. The Naismith platforms are just chunks of floor, mounted outside the telescope at the altitude pivot. That way, the light comes out from the telescope in a nice horizontally-directed beam that you can feed into an instrument sitting on the platform.]
Plot seed:
Ambitious observatory director Dr Smith got money from a poorly-identified charitable foundation to build the world's largest telescope, which has been completed and commissioned. Though it was never officially announced, a condition placed by the contributor is that one of the telescope's Naismith platform is premanently dedicated to the equipment supplied by the mysterious foundation, and they also get 25% of the time on the telescope. (Standard scientific instruments are mounted at the other platform, and there's no mystery at all about those or the people using them.)
What's on that platform? It's not some rich folks and an eyepiece, that's for sure. It's not even clear whether they are using it to observe; you can shoot beams out a telescope -- which has pointing accuracy unmatched by any other human technology -- simply by pointing the beam out the way the light came in.
Test-bed for anti-satellite weapons? Uplink for orbital mind control lasers? Downlink for instructions from Hastur (last known whereabouts: Aldebaran)? What's there? And who is the mystery foundation that gave $300 million for the telescope, and why is it so hard to find out who they are?
