Additional Features
Scanlan Observatory
Housed atop the iconic blue Charles E. Cheever, Jr. Star Tower, the Scanlan Observatory houses a 10-inch refractor telescope and features a 360-degree rotating dome, enabling stargazing in any direction. The adjacent Powell Star Deck accommodates up to 50 guests for a rooftop star gazing experience or an outdoor classroom for astronomy students.
The Scanlan Observatory is only available on Friday evenings in two viewing sessions at 9:30pm and 10:30pm. Observatory availability is subject to weather conditions and availability of staffing. When available, a limited number of single price $3.00 tickets are only sold at the Lackey Camp Casper ticket booth in the center. Guests attending the 9:30 p.m. presentation may purchase observatory tickets at the time of their planetarium purchase. Tickets will not be sold during evenings of extreme temperatures or cloud cover and will never be sold in advance online.

Our planetarium programs are designed to be “grade-specific.”
