NIU Observatory

One of the best-kept secrets at NIU is the Davis Hall observatory, which overlooks the East Lagoon.

The primary goal of the Observatory is to serve as an educational resource for NIU students and the northern Illinois community. The public is invited to visit the Observatory for telescope viewing whenever NIU is in session. Viewing is free and the public is welcome. You can also check out the video produced by the Northern Star.
