The Latest News & Upcoming Events
Dr. Lance Simms will talk about the history of astronomical imaging. Most people know that
Galileo revolutionized the field of astronomy when he pointed a telescope up at the heavens in
1610. What is not as widely known is that a similar revolution occurred when John William Draper
first moved away from the human eye as the primary astronomical sensor in 1840 and used
photographs instead. In this talk, Dr. Simmms will give a brief overview of the history of
astronomical imaging and the incredible impact it has had in the fields of astronomy,
astrophysics, and cosmology. Along the way, he will delve into a bit of detail on how modern
Charge Coupled Devices and CMOS imagers work.
Lance Simms is a physicist/engineer at Lawrence Livermore National Laboratory. He received a BS
in Physics from University of California: Santa Barbara in 2003 and a PhD in Applied Physics from
Stanford in 2009. His PhD work focused on the application of Hybrid CMOS imagers in
astronomy. Nowadays he loves working with whatever detectors he can get his hands on (infrared,
visible, X-ray, you name it), and currently characterizes and programs imagers for optical
payloads in small satellites.
TVS will hold its annual board elections at the upcoming meeting on November 18th. Chuck Grant
will present the slate of candidates and election is by acclimation. The present nominations are:

Chuck Grant has decided to step down as President of the TVS. He has served for many years now
