The University of North Texas observatory in the Rafes Urban Astronomy Center is now charging $5 for its monthly star parties.
The star parties are held the first Saturday of each month about 30 minutes after sunset.
Children ages 4 and younger will still get in for free.
The goal is to improve people’s experience with new technology, said Anessa Mullins, the astronomy lab coordinator.
“We initiated the policy to allow us to develop our program with new technology,” she said.
The outreach program is not state-funded, she said, and charging admission will allow the observatory to upgrade the telescopes it uses for the outreach.
UNT is offering a $1 discount to people purchasing tickets for both the planetarium and the observatory.
The observatory will take cash or checks but doesn’t have the capability to process credit or debit cards, Mullins said.
The observatory is located at 2350 Tom Cole Road.
