Abstract: We describe a balloon-borne hard x-ray telescope called scintillation imaging gas-filled hard x-ray telescope (SIGHT). SIGHT is a high sensitivity, good energy resolution instrument that images in the 30 to 300 keV region. We discuss the development of a large area, 20 atmosphere, position sensitive xenon gas scintillation drift chamber which is the gamma-ray detector at the heart of the telescope package. Results of the development of the novel waveshifting fiber readout for this chamber are presented. !15
