Corwin's Notes

=====

NGC 3155 = NGC 3194.  NGC 3155 was found by JH and later remeasured by d'A.  
Their position, used in the NGC, is quite accurate.  NGC 3194 is from WH's 
sweep 1096 of 2 April 1801; all the nebulae in that sweep have large, 
systematic position problems.  See NGC 3752 for more.
