Rainwater Observatory and Planetarium is the site for the annual Midsouth Star Gaze.

This gathering of amateur astronomers is held in late March or early April each year on the weekend closest to New Moon (to allow for the maximum night-time observing for deep-sky objects such as galaxies and nebulae).

The planetarium/activities complex includes one main building with a 30-foot dome and Spitz planetarium projector, combined with a computer/activities room.

Various astronomical exhibits such as markers showing the arrangement of the Stonehenge standing stones with their annual rise and set points, a multitude of sundials, and a walking trail that demonstrates the relative distances between the Sun and all its planets, cover the distance between the activities complex and the hilltop cluster of observatory buildings.

The video astronomy van is available for visits within approximately a 100-mile radius of French Camp.
