Overnight Telescope Observing Program (Formerly AOP) Request Registration Form

Please fill out this form completely before submitting. We normally offer the Overnight Telescope Observing Program during the two weeks over the new Moon in order to provide the darkest sky of the month. This is only a request form and does NOT guarantee your desired date. Requests for reservations for the OTOP are recommended at least 2-months in advance of the desired date due to high demand. Unlike the Nightly Observing Program, this program is not available on short notice.

We will do our best to book your desired date in the order of date preference. You may receive several communications from our OTOP Coordinator discussing your needs, desired dates, and preferences for the type of viewing you seek. Only after all details are arranged will you reserve a program confirmation. Your reservation will not be complete until you receive the Reservation Confirmation E-Mail.

You may register online using credit cards (American Express, MasterCharge, VISA or Discover) by clicking Proceed to OnLine Registration.


Please call 520-318-8330 with any questions that you may have. We look forward to you joining us!
