The observatory's main instrument is a custom designed 16-inch Newtonian-Cassegrain reflecting telescope. The mirror was figured at Kitt Peak Observatory. The telescope was designed and built by club members and local industries. The telescope is mounted on a custom German equatorial mount. Attached to the main telescope is a 6-inch refractor which is used as a guide scope. A 5-inch astrograph refractor can also be attached to the telescope.
