Edmond Halley's Telescope

Origins
Edmond Halley was an English astronomer, geophysicist, mathematician, meteorologist, and physicist who is best known for computing the orbit of the eponymous Halley's Comet.

Effects
When the magnifying lens is pointed facing the sky, it attracts various space junk and debris to Earth. This can include satellites, comets, spacecraft and even high flying aircraft. Reversing the telescope so that the viewing lens is facing upwards will repel the debris and create a clear airspace.

Leveling the telescope out will neutralize the effects, drawing things back into their original orbit with unexpectedly strong gravitational pulls.
