BOK :The 90'' (2.3 m) Bok Telescope on Kitt Peak is the largest telescope operated solely by Steward Observatory. BOK/BASS :The Beijing-Arizona Sky Survey (BASS) is an ambitious wide-field multicolor survey of 5000 deg2 of the Northern Galactic Cap using the 90prime imager on the 2.3m Bok Telescope at Kitt Peakid:BOK/BASS.a → GaiaXPy base XML file.
