Special Interest Groups
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 (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! For more information, just follow this link...
