Reconfiguration of Mimir on back of telescope. Note ARC array control electronics moved to south side of autoguider, Electronics rack tucked up closer to back of primary mirror cell. The old "saddlebags" configuration of the electronics and array controller failed to avoid collision with the floor of the dome at some pointings, though the cryostat avoided the floor for all pointings. |
