The Dearborn Observatory is open for public observing with the historic 18.5" refracting telescope every Friday night from 9-11 pm.
The Friday sessions are open to anyone and there are two options for visiting:
| 9 to 10pm: One hour session by reservation only. Your group will be able to use the telescope for the full hour. |
| 10 to 11pm: Walk-ins are welcome but space in the dome is limited. Therefore, there is no guarantee of getting to use the telescope if we are very crowded. |
There is no charge for these Friday night events; however, we do require a refundable deposit for large group reservations. Additionally, the Dearborn is available for private viewing events on other evenings. Please call the Astronomy Department at (847) 491-7650 for more information or to place reservations.
