Abstract: A tip/tilt off-load function from AO188 deformable mirror mount to Subaru telescope infrared secondary mirror has been implemented and tested. The function is effective to reduce the influence of strong background pattern at thermal infrared wavelengths. We describe the function and report the test results in this paper.
