Emory University stimulates interest in Astronomy with DFM 24" Telescope and TCSGalil Upgrade
Located within the silver dome atop Emory University's new Mathematics and Science Center, the 24" Cassegrain telescope is the centerpiece of the physics department's new astronomy program and one of the major attractions on campus.
This modern DFM 24" Telescope is computer controlled by a recently installed telescope control system (TCS) called TCSGalil. The telescope's 24" mirror affords it the "light gathering" ability to see deeply into the universe and the new TCSGalil provides ease of use and numerous practical benefits.
Emory scientists are using the new telescope and the data collected in astronomy, photometric measurements and spectroscopy.

DFM contributes to the Asteroid Terrestrial - impact Last Alert System (ATLAS) at the Research Corporation of the University of Hawaii (RCUH).
RCUH and the Institute for Astronomy (IfA) at the University of Hawaii have developed a project called the ATLAS. It is designed to compliment the Pan-STARRS project for locating Earth bound asteroids and comets.
ATLAS will be a vital alert system for incoming planetary disasters, namely, asteroids. Astronomers expect the ATLAS system to be fully operational by the end of 2015.
