The Delta Dome is Delta College's newly constructed on-campus observatory. We are
excited to share this incredible resource with our students and the broader community.
The Delta Dome serves as a hub for astrophotography, astronomical research and education.

The Delta Dome houses a CDK700 telescope with a 28-inch mirror installed by PlaneWave Instruments of Adrian, MI. The telescope provides the Great Lakes Bay Region with stellar views of galaxies, nebulae and other deep space objects. This observatory project came to fruition after years of planning and funding from Delta College. Additional grant dollars from the Michigan Earth Science Teachers Association (MESTA) and the Great Lakes Star Gaze Committee (GLSG) allowed for the purchase of a high-quality imaging camera.
During observation nights, attendees will have the chance to view celestial bodies through the telescope, with guidance from faculty. Regularly scheduled public observation events align with new Moon phases and ideal weather conditions.
The Delta Dome is located on the west side of the Delta College Main Campus just behind
the Athletic Field House (concessions). For information on upcoming public Delta Dome
events, call 989-686-9232.
