DAS Home

The Delaware Astronomical Society's purpose is to encourage interest in and share our passion for astronomy. We do so throughout the year partly through star parties, a monthly on-line newsletter and having interesting guest speakers from various fields of astronomy at our meetings. These are only a few of our offerings to the members of DAS and the public at large. On this site, you will find our calendars, much more club information, items of interest to amateur astronomers, and lots of other information. Membership is not required to attend our meetings. Information on joining DAS is available at How to Join DAS.
