Welcome to Selu Observatory

Radford University's Selu Observatory is a remarkable resource for Radford, the surrounding counties, and all of southwest Virginia. A few miles from Exit 109 off I-81, its location makes it possible for Radford University students, school groups, families and interested local citizens to have the wonders of the universe available in a convenient setting. The observatory makes the planets, stars, comets, and other celestial bodies immediately accessible to view. It allows researchers to investigate the dynamics of the universe, and it allows interested amateurs to see first hand the intriguing objects in space that affect tides, weather, seasons, and other aspects of our lives. School children can gain exposure to technology that will help them develop an interest in science.

Selu Observatory is free and open to the public every clear Friday night. Sessions usually last about two hours, but may run longer or shorter depending on interest and sky conditions. Many interesting objects can be seen throughout the year.

First Light

First light is when a telescope is first used to take an astronomical image after it has been constructed. The first light image is normally of little scientific interest and is of poor quality since the various telescope elements must be adjusted for optimum efficiency. Usually, a well-known and spectacular astronomical object is chosen.

First light is always a moment of great excitement, both for the people who designed and built the telescope, and for the astronomical community.

This photo of the moon was taken with a digital camera held up to the 31mm eyepiece.
