6:30 p.m. — Filters to improve visual and photo astronomy
[Tentative: The use and abuse of optical filters for visual observing and astrophotography, applied to both bright and dim celestial sources. Not just what to use — because that is a complicated question — but why certain filters might help your equipment and your applications.]
Alan is a member of NOVAC since 2001, currently serving as VP, and is a principal scientist with The MITRE Corp. in McLean, VA. He’s been an amateur astronomer since elementary school, and observes with an 8” SCT. He is fascinated by manipulating and learning from light, from the source through etection and processing, to understanding. After graduate study at Univ. of Texas and MIT in astronomy and planetary science, he worked on the design and operation of the Hubble Space Telescope, principally the interferometer star tracker and Guide Star Selection System. He then worked on Landsat, NASA’s Terra-Aqua-Aura series, and NOAA’s NPOESS weather satellites. He currently assists the government in satellite remote sensing data and systems.
