From April through October, the TCAA holds monthly observing sessions that are open to the public. These "star parties" are held at our observatory at the Sugar Grove Nature Center, a dark sky site southwest of Bloomington.

Additional prominent sky objects such as planets, nebulae, star clusters, and galaxies will be viewed when visible.
