NGC/IC Project Restoration Effort

===== NGC 4884 = NGC 4889. As with NGC 4882 = NGC 4886 (which see), the only problem with d'A's observation is the RA offset on one night. Otherwise, his observation is appropriate: "Brightest of a multiple nebula ..." In this case, he has seven other observations which he attributes to this galaxy. Among these are two made on the two nights previous to his NGC 4884 observation, 20 and 21 April 1865. So, I'm surprised that he did not immediately recognize the field that he had swept over twice on the previous nights -- this is a strikingly rich field, and his observations of the galaxies in the Coma Cluster are liberally sprinkled with comments to that effect. I would have expected his visual memory to kick into overdrive, but if it did, he chose to ignore it. So, for whatever reason, he entered the observations as if for separate objects, so they ended up in the NGC as numbers 4882 and 4884. See NGC 4872 for a general discussion of d'A's observations in the Coma Cluster core.
