  The results of a search for peculiar astronomical objects using very low
resolution spectra obtained with the NASA Orbital Debris Observatory (NODO) 3
meter diameter liquid mirror telescope (LMT) are compared with results of
spectra obtained with the Sloan Digital Sky Survey (SDSS). The main purpose of
this comparison is to verify whether observations taken with this novel type of
telescope are reliable. This comparison is important because LMTs are a novel
type of inexpensive telescope that are very useful for astronomical surveys,
particularly surveys in the time domain, and a validation of data taken with an
LMT, by comparison with data from a classical telescope, will validate their
reliability. We start from a published data analysis that classified only 206
of the 18,000 astronomical objects observed with the NODO liquid mirror
telescope as peculiar. A total of 29 of these 206 objects were found in the
SDSS. The reliability of the NODO data can be seen by the results of the
detailed analysis that, in practice, less than 0.3% of the 18,000 spectra were
incorrectly identified as peculiar objects, most probably because they are
variable stars. We conclude that the liquid mirror telescope gave reliable
observations, comparable to those that would have been obtained with a
telescope using a glass mirror.
