600/800mm - 24" (6/4/16): at 322x, VV 128b, the fainter member of Arp 260, appeared extremely faint, very small, no structure but confirmed. Situated just off the northeast end of VV 128a, 35" from the center of the main galaxy. CGCG 098-101, located 7.7' WSW of VV 128, appeared fairly faint, small, round, 18" diameter, slightly brighter nucleus.

24" (5/30/16): at 225x; Arp 260 = VV 128 (pair of interacting blue galaxies) appeared faint, fairly small, elongated ~2:1 SSW-NNE, 0.8'x0.4', irregular surface brightness, slightly brighter core. Occasionally a 16th mag star was seen at the northeast end (0.4' from center). A mag 15.3 star is 1' SW. CGCG 098-102, located 12.7' NW, appeared fairly faint, round, 20" diameter, easily visible continuously.

900/1200mm - 48" (4/30/19): at 545x; Arp 260 = VV 128 = UGC 7230 is an interacting pair of disrupted spirals with centers 0.6' apart SW (VV 128a) to NE (VV 128b). The SQM readings hit 21.98 at the time of the observation!

VV 128a: between fairly faint and moderately bright and large, uneven surface brightness, very irregular shape but roughly elongated 3:2 with an ill-defined halo. A brighter spot was noted SW of center; this is probably the core/nucleus. A mag 16 star is just off the NE end.

VV 128b: between faint and fairly faint, fairly small, very elongated 3:1 NNW-SSE [central bar], ~20"x6". A mag 16 star is 0.2' W of center.
