SPECTRE is a proposed 0.4-4.2 µm low-resolution spectrograph being developed for the NASA Infrared Telescope Facility. Dispersion is accomplished using prisms to optimize throughput, resulting in a mean resolving power of R=160. SPECTRE has an image-slicer integral field unit with a 7.2′′ field of view to remove slit losses, reduce mechanical complexity, and enable precision spectrophotometry. Dichroics are used to divide the light into three spectroscopic channels, each with optimized optics and its own detector. We will use a 2K frame transfer CCD for the optical channel, and an H2RG in each of the two infrared channels. SPECTRE is a single mode instrument: there are no moving optics and the spectral format is fixed, making for a simple and rigid instrument. Guiding will be done by a co-mounted visible light camera with a 3′ field of view.
‘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
