Total Solar Eclipse
April 8, 2024
The Texas Astronomical Society of Dallas wishes to partner and participate with individuals, groups, schools, towns, and all forms of organizations to celebrate the 2024 total solar eclipse. This majestic celestial event will be, for many, a once-in-a-lifetime opportunity that is certain to inspire wonder about our place in the universe. We in North Texas are fortunate to sit on the path of totality, and with this opportunity we will provide education to whoever desires it.
Within this outreach kit, you will find in-depth information and ample resources to help you have a successful total solar eclipse viewing.
If you have questions about any of the content provided, or require further information regarding the science of eclipses, safety, or planned events, please feel free to reach out to us at info@texasastro.org, and follow us on Facebook and Instagram to stay up to date on our club’s events, news, and general membership meetings. And of course you can become a member of TAS at texasastro.org.

Special Interest Groups
APSig
APSIG (Astrophotography Special Interest Group) is sponsored by the Texas Astronomical Society of Dallas, Texas.
APSIG meets once a month to share information and learn more about the art and science of Astrophotography -- taking photographs of objects in the night sky such as planets, galaxies, nebulae, and star clusters. Imaging these celestial objects requires special techniques and equipment, but are attainable by anyone willing to point their camera skyward. Come learn how! For more information on APSIG just follow this link.

ATMSig
ATMSIG (Amateur Telescope Makers Special Interest Group) is sponsored by the Texas Astronomical Society of Dallas, Texas.
The ATMSIG meets every other month to explore the design, construction and adjustment of both do it yourself and professionally built telescopes. Anyone interested in building their first scope will find this group a big help in finding the best place to start. You don’t need to have a well equipped workshop, just a few simple tools and an interest in building or modifying it yourself. The ATMSIG is a wonderful place to see projects built locally by TAS members and to share new ideas for the future!
Please Note: ATMSIG is currently inactive.
