Welcome to the Society for Astronomical Sciences
The SAS/AAVSO-2020 Symposium has been changed to an online event. See the “Symposium” tab for more information.
Science with Small Telescopes
Amateur and professional astronomers are using small telescopes and modern instruments to conduct astronomical research in a variety of areas.
- The size, shape, and rotational state of asteroids are determined by occultations and lightcurves.
- Continuous monitoring of planets provides context between large-telescope and spacecraft observations.
- Lightcurves of eclipsing binary stars and astrometry of visual double stars contribute to assessment of stellar size and mass.
- Modest-resolution spectroscopy of transient objects can distinguish supernovae from imposters.
- Time-series photometry provides a wealth of data about variable stars.
- Long observing runs and exploratory projects that are impractical at large observatories can be pursued on small telescopes with astrometric, photometric, and spectroscopic capability.
What We Do
- Foster interest and participation in astronomical research by backyard and student astronomers
- Increase awareness of small-telescope capabilities and data to support the professional research community.
- Facilitate collaborations between professional and amateur astronomers.
- Encourage publication of relevant results.
- Provide a forum for networking, learning, and sharing experiences.
In 2019, the Symposium on Telescope Science celebrated its 38th year. This has become one of the premiere pro-am events with 100-150 participants giving papers, attending workshops, and networking with fellow researchers.
If you're interested in devoting even a little of your telescope time to astronomical research, the Society is the place to find others with a similar interest in unlocking the secrets of the Universe. Come join us!
