Optimized for infrared observations, the NASA IRTF utilizes a f/37 Cassegrain focus that produces an image scale of 1.84 arcsec / mm over an unvignetted field-of-view approximately 2 arcminutes in diameter. Location ======== The observatory location data given here are geodetic latitude and east longitude, based on values from the Astronomical Almanac, 1989. The geocentric site radius was determined using the MERIT 1983 earth figure, equatorial radius = 6378.137 km and flattening of the reference spheroid = 1/298.257.
