New Telescope Attachment Allows Ground-Based Observations of New Worlds 2 (image) Penn State Share Print E-Mail Caption A team of astronomers led by researchers at Penn State have developed beam-shaping diffusers -- small pieces of etched glass that can be mounted on telescopes -- that increase the quality of ground-based photometric observations. The research team tested the diffusers on the 3.5m telescope at Apache Point Observatory in New Mexico (left; image credit: Gudmundur Stefansson), the 5m Hale telescope at Palomar Observatory (middle; image credit: Caltech/Palomar Observatory), and the 0.6m telescope at Davey Lab Observatory at Penn State University.
