AAVSO How to [Understand Star Photometry]

Originally broadcast March 5, 2022. Instructor: Richard Berry. Berry is well experienced in stellar photometry and was a programmer for the science-oriented software Astronomical Image Processing for Windows (AIP4Win). Photometry seems like magic: you click on a star image and a magnitude pops up! But a lot happens between the moment you "click" and the moment that magnitude pops up on the computer screen. Berry explores with you--in non-technical terms--what the computer has to do to turn your pixels into meaningful information. This talk complements Bob Buchheim's "Introduction to Photometry" 2021 webinar (   • AAVSO How-To Hour: How to Start with CCD P...  ). Berry describes how to do photometry by presenting the inside picture of how photometry works and why it works so well. He demonstrates using AIP4Win software (join [email protected] to download this freeware package), but all stellar photometry software works pretty much the same way.
