The Kahale Observatory is located on the central Oregon Coast. Currently it consists of a three fully automated astrophotography systems, a NexDom 8' observatory with a 10Micron mount on a pier, a field unit using a CGX-L mount, and a mobile unit with a CGE-Pro mount. 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 all skycameras, a rain and a cloud monitor.
