With a primary mirror of 36 inches, the 0.9-Meter
Telescope is the smallest research telescope operated by
Kitt Peak National Observatory. Yet, it remains a major wide-field
imaging telescope. The CCD Mosaic Imager on this telescope affords
a 1 degree field of view, a uniquely powerful combination.
contributions of the 0.9-Meter
Telescope are numerous. The telescope has been used to investigate
an extensive network of photometric standard stars as well as
in stellar photometry of variable stars and of stars in clusters.
The 0.9-meter participated in studies of the morphology of a
wide variety of extended sources including planetary
nebula, H II regions, and galaxies. Also, the facility has
contributed to imaging surveys including clusters of galaxies,
samples of rare objects such as emission-line galaxies or dwarf
C stars, large-scale structure, and the Galactic halo.
