Dec -17°42.5'
Galaxy

Steve Gottlieb, observing with a 17.5-inch, notes: “faint, fairly small, very elongated 3:1 SSW-NNE, 1.5'x0.5', no concentration. Brightest in Hickson 21 with N1100 4.5' ENE and N1098 6.4' NW.”

Galaxy

Steve Gottlieb, observing with a 17.5-inch, notes: “faint, fairly small, elongated 5:2 WSW-ENE, weak concentration. Similar appearance as N1099 4.5' WSW. A mag 14 star is off the SE side 1.7' from the center and a mag 13 star is 2.3' NNE. About 9' N is pair of faint galaxies; N1091 = Hickson 21E and N1092 = Hickson 21D.

The RNGC (Sulentic and Tifft 1973) notes that this is a 13.0 mag galaxy. Their coded description reads EL,BM,STRSUSP INDSK.

Galaxy

The RNGC (Sulentic and Tifft 1973) notes that this is a nonexistent object. Their coded description reads NF S.

Steve Gottlieb, observing with a 17.5-inch, notes: “very faint, very small, round, 20" diameter, weak concentration. Forms the W vertex of a near equilateral triangle with a mag 10.5 star 3.0' NE and a mag 12 star 3.5' SE.”
