LVAAS General Meeting

Sunday, February 14 at 7:00 p.m.


Astro Dynamics:  Fun with M1, M13, M27, M51, and Betelguese...

We amateur astronomers look at, and photograph, beautiful star-clusters, nebulae, and galaxies.  When we look at two pics of the same object taken days or months or years apart, they usually look the same.  It seems like a static universe.  But, it's not.  Changes do happen.  In this talk, I will show several pairs of pictures showing that things do change.  And, I'll discuss what causes these changes.

Robert Vanderbei

Bob first became interested in the stars in the summer of 1963, when he was 7 years old and the family did a camping trip around Lake Superior.  He woke up in the middle of the night, went outside the tent, looked at the sky and was astonished by the beauty of the stars. He was an active amateur astronomer until his High School years, and returned to the hobby at about the turn of the century. He has been an active astrophotographer since shortly thereafter.

Bob did a BS in Chemistry at Rensselaer Polytechnic Institute (RPI) and a PhD in Applied Math at Cornell, and worked at AT&T Bell Labs' Math Research Center in Murray Hill NJ before joining Princeton University in 1990. During his career he contributed to designing a NASA space telescope to image Earth-like planets.

Since 2005 his amateur setup has included a Takahashi FSQ-106N and a 10" Ritchey-Chretien telescope from RCOS. He has had the pleasure of taking many astrophotos from the driveway at his house just 8 miles north of Princeton.

He's also co-written a book with J. Richard Gott entitled "Sizing Up The Universe". It is published by National Geographic.

THE LEHIGH VALLEY AMATEUR ASTRONOMICAL SOCIETY -- 620B East Rock Road -- Allentown, PA 18103 -- 610-797-3476 -- www.lvaas.org

WELCOME!

Founded in 1957, the Lehigh Valley Amateur Astronomical Society (LVAAS) is one of the oldest continuously-operating amateur astronomy organizations in the U.S. The mission of LVAAS is to promote the study of Astronomy and to maintain a meeting space, observatories, and a planetarium.

LVAAS operates two astronomy sites: The South Mountain site in Salisbury Township is the headquarters of the Society. It has a planetarium with a Spitz A3P projector, a 21 foot dome, meeting space, the Red Shift store, library, workshop space, and three observatories. The Pulpit Rock site near Hamburg is LVAAS's members-only dark sky site. At 1600 feet above sea level, the site features five observatories and a pad for member's scopes.

Members who receive training on the scopes may obtain keys to the observatories. LVAAS also maintains a rental "fleet" of telescopes that members may rent at low cost. Members also receive access to The Observer, our online newsletter, as well as reduced subscription prices to Sky and Telescope and Astronomy Magazine. If you want to learn more about astronomy and LVAAS, please join us at our next public star party.
