ROTSE IIIb Telescope
The Robotic Optical Transient Search Experiment has placed telescopes in four locations on Earth to cover the entire sky in search of gamma-ray bursts. One of these, ROTSE IIIb, is located at McDonald Observatory. In addition to its primary mission, the telescope is used for the ROTSE Supernova Verification Project (RSVP).
