The facility's observatory dome hosts a computer-based 45 cm (1.48 ft) Cassegrain reflector telescope^[1][2] installed at the site in May 2001 and donated by the Japanese government through a cultural aid grant.^[3] Before this period, the observatory used a 30 cm (0.98 ft) reflector-type telescope.^[1] The current telescope is often used for CCD imaging of stars.^[2]

The PAGASA Observatory was opened for public use on February 16, 2003, during National Astronomy Week.^[1]
