Thanks for your review! We're sorry to hear that you were disappointed by your visit to the observatory. Going on tours and attending talks is the best way to experience the observatory, but we also have scheduled open houses at various buildings throughout the day. The Giovale Open Deck Observatory has various exhibits to view on the plaza, even when the observation deck is closed. If you have any further feedback, please feel free to reach out to us at info@lowell.edu. We hope you come back to visit the observatory in the future so that we can provide an experience that exceeds your expectations.
