===== NGC 4898 = NGC 4894 is a double galaxy in the Coma Cluster, first seen by JH; it was also seen by d'A and by Bigourdan (who calls it "NGC 4894"). See NGC 4864 and NGC 4872 for more on the observations in the Coma Cluster that led to the NGC numbers that we use today. Also see NGC 4894 for more on the identity of that object to this one. Bigourdan also reports an observation for "NGC 4898", measured with respect to his comparison star "b" (see NGC 4875 for the story about this). That observation, however, points at a blank area "... roughly on the line joining GC 3354 and 3351 [this galaxy and 4889, respectively], and follows these nebulae." This is an appropriate description of the position that we reduce from his measurements, but there is nothing at all in that position. This must have been another of his "fausses images".

===== NGC 4898 18" (4/20/12): this double galaxy is the brightest close-in companion to NGC 4889 in the heart of the Coma cluster. At 282x it appeared fairly faint to moderately bright, small, oval 4:3 E-W, mild concentration to center. Occasionally, the companion (NGC 4898B = PGC 3098454) popped as a stellar or nearly stellar knot on the east end of the galaxy. Located 2.5' SE of NGC 4889. CGCG 160-247, just 45" NNW, is identified as NGC 4894 in modern sources. At 282x, this challenging galaxy appeared extremely faint, very small, round, 10" diameter. The small dimensions imply I only picked up the brighter core and missed the extensions SW-NE. 17.5" (4/21/90): located in the central core of AGC 1656 cluster 2.5' SE of brightest member NGC 4889. Faint, very small, slightly elongated. This is the last of four on a line with NGC 4894 just 45" NW, NGC 4889 2.5' NW and NGC 4886 3.5' NW. 13" (5/14/83): faint, small, slightly elongated. Located 3' SE NGC 4889 in AGC 1656.
