The Kahale Observatory is located on the central Oregon Coast. Currently it consists of three fully automated astrophotography systems, a NexDome 8' observatory with a 10Micron mount on a pier and a field unit using a CGX-L mount and a Dwarf 3. Three different OTA's can be attached: a Celestron 14" SCT, Celestron 11" SCT and a Explorer Scientific 152mm refractor. The imaging stack includes a 7 position filter wheel and the ZWO 2600 pro, ZWO 1600 pro or a ZWO 294 color pro imager. It includes weather, telescope and dome monitoring equipment plus allskycameras and a rain and cloud monitor. The C14 includes optional HyperStar and .7 reducers.
