William Herschel discovered NGC 5529 = H III-414 = h1764 on 1 May 1785 (sweep 405) and recorded "vF, vmE." JH made the single observation "pF; vmE; a long narrow ray pos = 110.3° by micrometer; vgvlbM; 90" l, 12" br." R.J. Mitchell, observing with LdR's 72" on 19 Apr 1855, recorded "long narrow ray with a S, R, vF neb sf..." The second object is certainly CGCG 191-071, which was not assigned a GC or NGC designation.

400/500mm - 17.5" (5/27/95): faint, large, edge-on ~8:1 ratio WNW-ESE, 3.5'x0.4', weak concentration. Two nearby mag 14.5 stars are 1.4' S of center and off the ESE extension 3.0' from center. Forms a close pair with MCG +06-31-087 3.8' SE. NGC 5557 lies 38' ENE.

900/1200mm - 48" (4/22/17): bright, very large, thin edge-on ~8:1 or 9:1 WNW-ESE, 5'x0.6'. Contains a bright, very elongated core or central region that slightly bulges with long thin extensions. A low contrast dust lane runs through the central 1/3 or 1/2 the galaxy, slicing the galaxy asymmetrically with the main brighter portion on the south side of the lane. A mag 14.6 star is at or just beyond the ESE tip. A striking 1' string of three mag 11/13/13.5 stars is ~5' ESE of center.

LEDA 2076904 (V = 17.0), is just north of the east-southeast end of NGC 5529 and 2.9' ESE of center. It appeared faint, very small, slightly elongated, ~15"x12". CGCG 191-071 (V = 15.0), 3.6' SE of center, appeared fairly faint, fairly small, slightly elongated N-S, 0.4'x0.3', weak concentration. This galaxy is the brightest of the nearby galaxies. MCG +06-31-085b (V = 16.8), 3.6' NE of NGC 5529, appeared very faint, very small, round, 15" diameter. A mag 14.5 star is 25" NW. These three galaxies are collinear roughly N-S.

2MASX J14151337+3610078, 5.5' SW of NGC 5529, appeared faint, very small, round, 6" diameter. A mag 15 star is 22" SSW. It was easily visible (V = 16.6) due to fairly high surface brightness. MCG +06-31-085a, 3.4' SW of NGC 5529, appeared very faint, fairly small, round, 18" diameter. Very low even surface brightness with no zones. This galaxy is misidentified as NGC 5527 in RNGC, PGC, SIMBAD and WikiSky, but it is much too faint to have been discovered visually.

Finally a close trio of galaxies (two interacting) lie ~9' E of NGC 5529. LEDA 2076761 is fairly faint (V = 15.7), very small, round, 12" diameter. LEDA 2076843 (V = 15.0) appeared fairly faint, small, round, 15" to 18" diameter. A tidal arm to the north was not seen. Just 18" SE is 2MASX J14161954+3612404 (V = 16.2), logged as very faint to faint, extremely small, round, 6" diameter.
