Visitor Policies

The Wilder Observatory on Snell Street is free and open to all, starting at 9 p.m. every clear Saturday from April through October. Depending on what is in the sky at the time, vistors may see the moon, planets, asteroids, comets, multiple stars, star clusters, nebulae, galaxies and more through the large, world-class refractor telescope. Students, faculty, staff, community members, family and friends are welcome.

Young Visitors

The Observatory was originally designed academic research, but children and their caregivers are welcome and frequently part of visiting groups. As the equipment and facilities are quite old we ask that children be well-supervised. 

Personal Items

Personal items may be brought with visitors into the observatory.
