Summary: | An inspection of the DSS and 2MASS images of selected Milky Way regions has
led to the discovery of 66 stellar groupings whose morphologies,
color-magnitude diagrams, and stellar density distributions suggest that these
objects are possible open clusters that do not yet appear to be listed in any
catalogue. For 24 of these groupings, which we consider to be the most likely
to be candidates, we provide extensive descriptions on the basis of 2MASS
photometry and their visual impression on DSS and 2MASS. Of these cluster
candidates, 9 have fundamental parameters determined by fitting the
color-magnitude diagrams with solar metallicity Padova isochrones. An
additional 10 cluster candidates have distance moduli and reddenings derived
from K magnitudes and (J-K) color indices of helium-burning red clump stars. As
an addendum, we also provide a list of a number of apparently unknown galactic
and extragalactic objects that were also discovered during the survey. |
