Astronomical Society

Welcome to the Longmont Astronomical Society

The Longmont Astronomical Society is a non-profit amateur astronomy club based in Longmont, Colorado. The club was founded in 1987 by people enthused about astronomy and who were looking for an avenue to share their enthusiasm with others of like interest. Since then the club's membership has grown to over 100 (both families and individuals) that embody all levels of experience and interest.  All of the photos at right were taken by members of the club.

Our meetings and star parties are open to the public, and all are encouraged to attend.

Our Galaxy: the App and the Real Thing

by Bill Tschumy

Amateur astronomers generally know where to find deep sky objects in the night sky, but few are aware of their physical locations within the Galaxy. 

Our Galaxy is a new app for iOS and macOS (and soon for Windows and Android) that helps you understand the structural components of the Galaxy and visualize the locations and physical properties of deep sky objects in and around it.

Bill will discuss the creation of Our Galaxy and use the app to illustrate what we know about galactic structure and show where some well known deep sky objects are located within and around it.

About Bill...

Bill Tschumy, current LAS president, founded Otherwise Software in 1992 to develop innovative software.

Besides programming, Bill’s other interest is amateur astronomy and astronomy education.   In 2009 he got the chance to combine his programming skills with his love of astronomy and co-authored SkySafari, one of the most popular astronomy apps for mobile devices and Macintosh.

Bill has since left the SkySafari project and is now obsessed with understanding where the deep sky objects we observe are actually located in the Galaxy.  The Our Galaxy app is the latest result of his efforts.
