Observations, analysis techniques, and photometric properties of a mul
ti-narrowband survey of a 20 deg(2) area of sky at +33 degrees declina
tion are described. The survey is conducted with the 3 m liquid-mirror
telescope of the NASA Orbital Debris Observatory using intermediate-b
andwidth filters. These filters have central wavelengths ranging from
455 to 948 nm, at intervals of 0.01 in log lambda, and give a spectral
resolving power of Delta lambda/lambda similar to 44. In two spring o
bserving seasons, we have completed observations in 16 bands. Our prel
iminary object catalog contains over 10(5) detections to a typical 50%
completeness limit of m(AB) similar to 20.4. The survey is expected t
o provide object classifications, spectral energy distributions, and m
ulti-narrowband redshifts for similar to 10(4) galaxies and QSOs for u
se in studies of galaxy and QSO distributions, evolution, and large-sc
ale structure. It will also provide photometry and spectral classifica
tions for over 10(4) stars.
