Observatory Open House is every Friday evening, WEATHER PERMITTING, starting at dusk.

Please come and observe the stars and planets with us, on any Friday evening that looks like “clear skies.”

Enter the Bloomberg Center for Physics and Astronomy, and take the elevator to the fifth floor. Directions are posted. Observing continues as long as conditions remain good.

Another chance to observe the heavens at the Maryland Space Grant Observatory occurs after each Open Night Lecture at the Space Telescope Science Institute. These lectures are given on the first Tuesday of every month.

Are you a student at Morgan State University, or at Johns Hopkins University? You may wish to be trained to operate the telescope yourself. Apply to Ivelisse Cabrera at

Maryland Space Grant Observatory is a facility of the Maryland Space Grant Consortium, which also provides support to the University of Maryland Observatory.

General Information
The Morris W. Offit Telescope is the major observing instrument in Maryland Space Grant Observatory,
This telescope was provided by an anonymous donor, in honor of Morris W. Offit, past Chairman of the Board of Trustees of Johns Hopkins University. The telescope has, as its major optical element, a 20″-diameter (that is, half-meter diameter) parabolic mirror. This f/8 Cassegrain telescope was built by DFM Engineering of Longmont, Colorado.

The telescope is located under the Stanley D. and Joan F. Greenblatt Dome, on the roof of the Bloomberg Center for Physics and Astronomy, on the Homewood Campus of The Johns Hopkins University in Baltimore, Maryland.

(This is not the only Morris W. Offit Telescope! The original telescope is at Apache Point Observatory where it is serving as the Sloan Digital Sky Survey monitor telescope. That 1/2 meter telescope observes the transparency of the atmosphere so that systematic images from a 2.5-meter telescope will be consistent over time. This is a crucial element of the survey, which will provide spectra for a million objects over 1/4 of the sky, and positions for more than 100 million celestial objects. More information about the sky survey can be obtained from the Sloan Digital Sky Survey website at Hopkins, or the SDSS website at Apache Point Observatory.)
