Abstract

‘Opihi is a 0.43 m, 32′ field of view (FOV) finder scope that rides along with the NASA Infrared Telescope Facility (IRTF), a 3.2 m infrared-optimized telescope near the summit of Mauna Kea, Hawai‘i. The main purpose of ‘Opihi is to recover Near-Earth Objects (NEOs) with positional uncertainties larger than can feasibly be found with the 1 ′ FOV of IRTF. Automated data collection with ‘Opihi will be useful for bootstrap photometry and can provide general context observing images. We present the design and commissioning process for ‘Opihi, including its photometric performance and first asteroid detection results
