03/06/09 - The 0.9m is no longer using dry Nitrogen as its main source to keep the dewar window clear of moisture. The 0.9m is now using a dry air system. The system is located in the back of the computer room and is routed through the existing N2 system. The dry air system needs power to run. In case of a power outage (or lighting shutdown) the N2 system will kick in as a backup. Normal dry air operation will resume once power is restored. Updates have been made to the manual to reflect this.
03/16/05 - Operation of the exhaust fan at the back of the telescope has changed slightly. The Startup and Shutdown checklists as well as the section on the exhast fan have been modified to reflect this.
03/16/05 - Dome slit opening/closing function has been restored to the control panel on the platform. Edited the Startup and Shutdown checklists to reflect this.
