Special Interest Groups
Astronomical Do It Yourself SIG
The Astronomical DIY SIG is where members can 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 ADIY SIG is a wonderful place to see projects built locally by SAAA members and to share new ideas for the future!
Dark Sky Efforts SIG
In the Dark Sky Efforts SIG SAAA members can discuss light pollution and our efforts to preserve dark skies.
Why is this important? Because less than 100 years ago, everyone could look up and see a spectacular starry night sky. Now, millions of children across the globe will never experience the Milky Way where they live. The increased and widespread use of artificial light at night is not only impairing our view of the universe, it is adversely affecting our environment, our safety, our energy consumption,our heritage, and our health.
Lunar Observing SIG
If the Moon affects you, then the Lunatics Club is for you The Lunatics Club is our our lunar observing SIG. If you live in the light polluted city then don’t worry there are still plenty of sights to see on the moon. This group is a place to discuss viewing the moon and also to plan star parties where the moon is the primary target of interest. This will also be a place to help each other complete the Astronomy League’s Lunar Programs:
