      Comments Off on 2nd On-Telescope Test of Metrology Camera System

Last year Metrology Camera System (MCS) was shipped to Subaru Telescope of National Astronomical Observatory of Japan, in Hawaii. After onsite integration and test, we installed MCS to the telescope and carried out optical alignment and on-telescope performance tests in June and October 2018. (See this for details)  MCS is installed to the Cassegrain focus at the bottom of the… Read more »
