Corwin's Notes

=====

NGC 4851 is not = IC 839 (which see) which is about 2 arcmin south-preceding.  
Bigourdan observed both on the same night, and his accurate positions fall 
within a few arcsec of each object.

NGC 4851 does have a faint companion just north-following.  d'A may have
glimpsed this as his description says "resolved".  Bigourdan must have had the
same impression as his description mentions that N4851 may be "a very small 
[star] cluster."

Steve's Notes

=====

NGC 4851

17.5" (4/21/90): very faint, very small, elongated N-S.  This is a double system (not resolved although the components are oriented NNE-SSW) in AGC 1656.  IC 839 is a separate galaxy 2.0' SW.
