  In traditional seeing-limited observations the spectrograph aperture scales
with telescope aperture, driving sizes and costs to enormous proportions. We
propose a new solution to the seeing-limited spectrograph problem. A massively
fiber-sliced configuration feeds a set of small diffraction-limited
spectrographs. We present a prototype, tunable, J-band, diffraction grating,
designed specifically for Astronomical applications: The grating sits at the
heart of a spectrograph, no bigger than a few inches on a side. Throughput
requirements dictate using tens-of-thousands of spectrographs on a single 10 to
30 meter telescope. A full system would cost significantly less than typical
instruments on 10m or 30m telescopes.
