Thou art he to whom praises are ascribed in the southern heaven, and thanks are given for thee in the northern heaven. The imperishable stars are under thy supervision, and the stars which never set are thy thrones.
Internal optics allow for two plate scales and a variety of spectroscopic resolutions.
Internal mechanisms control the selected filter, focal plane mask, pupil mask alignment, grating tilt, and optical arrangement. All mechanisms are user controlled and can be used to rapidly reconfigure the instrument, which allows for substantial observing flexibility.
