Mahadevan9-2017 Telescopes

Three telescopes pointed at the sky

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 ARC 3.5m Telescope at Apache Point Observatory in New Mexico (left), the 5m Hale telescope at Palomar Observatory (middle), and the 0.6m telescope at Davey Lab Observatory at Penn State (right).
