Steve's Notes

===== NGC 4900 48" (4/7/13): this unusual galaxy visually appears like a barred ring. At 488x a bright nucleus is embedded with a weak bar, extending NW-SE. A slightly brighter knot is situated close northwest of the nucleus. A mag 11 star is attached at the southeast end of the galaxy, collinear with the "bar". A large, round halo extends 1.7' and is slightly brighter along portions of the outer edge, forming a weak ring with a slightly darker interior on either side of the bar. 17.5" (5/22/93): fairly bright, moderately large, round, 1.5' diameter. A mag 10.5 star is attached at the SE edge 41" from center. Even surface brightness except for a faint slightly elongated "knot" just NW of center which may be the central bar or an offset nucleus. 8" (5/21/82): fairly bright, small. Unusual appearance with a mag 10 star attached at the east edge and the galaxy extends to the west.
