HCAS conducts public open houses on one Saturday night of each month throughout the year. The general public is invited to these events which are held at the observatory. Parking is at the Vocational Technical High School parking lot which is adjacent to the observatory. The Observatory parking lot is reserved for telescopes. After parking, find the path that cuts through the trees and leads to the observatory driveway. You can find us on Google Maps by searching Harford County Astronomical Society. This address should also get you close. 208 Thomas Run Rd, Bel Air, MD 21015.
Please consider donating to the HCAS Observatory Maintenance Campaign to help clear some of the tree cover around the observatory, as seen below!
