Abstract

We detail the use of Engineered Diffusers to achieve precision ground-based photometry for exoplanet transit observations. These diffusers are inexpensive, easily scalable, and suitable for use on telescopes large and small to achieve some of the highest precision photometry from the ground. We provide updates on our ongoing ground-based diffuser-assisted transit follow-up program and detail key ways to incorporate diffusers in different telescopes.
