Taurus
is rich in dark nebulae, in the region between Iades and Pleiades and
the Milky Way. This is an example of an underestimated nebula, about
10° east of Pleiades.
The region is filled with many objects, each one with many catalog
numbers. The main ones are: Barnard 18 in the center, wide dark nebula
(alias LDN 1527); LBN812 is the bright part in the center; LDN1533 is
the dark nebula at left, with LBN 815 the yellow patch in the middle;
LDN 1522 is the dark nebula at right. They all are part of LBN800, a
very large complex including these and many others in a 5° patch of
sky.
