Join our Executive Director, Dr. Brian Kloppenborg, as he traces the journey of light from the stars to our sensors.
Brian's presentation explored the impacts which atmospheric transmission, telescope optics, and sensor technologies have on stellar photometric data, as well as how photometric filters and transformation processes serve to *standardize measurements* across observers.
Brian also discussed the most common photometric systems used by amateur astronomers, presented transmission curves of a variety of commercially available filters, and shared how you can use transformation to *improve the quality of your photometry.*
In true "How-To" fashion, we wrapped up with an extended Q&A session, diving into the nitty-gritty of photometry while answering questions from the audience.
If you want to improve your photometric accuracy by transforming your observations, this video is a must-see!
*Dr. Brian Kloppenborg* (Ph.D. Physics - Astrophysics Specialization) is an astrophysicist and entrepreneur. He earned a Ph.D. in Physics from the University of Denver, and a B.A. in Physics from Hastings College. Prior to joining the AAVSO, Brian worked as a Research Scientist at Georgia Tech Research Institute, where he served as a subject matter expert, lead engineer, product owner, and project director on a variety of government programs. He also ran a small business that provided data science, machine learning, and GPU accelerated computing services. Brian's research interests include photometry, spectroscopy, astrometry, and long-baseline optical interferometry of eclipsing binaries, novae, and young stellar objects. His work is published in Nature, ApJ, JAAVSO, and similar scholarly journals.
He became AAVSO Executive Director on September 16, 2022.
