600/800mm - 24" (3/28/17): Arp 198 is an overlapping pair consisting of face-on spiral (VV 267a) and a thin edge-on (VV 267b) that extends right to the nucleus of the face-on. At 260x and 375x, the edge-on appeared as a very faint, fairly small, very elongated glow, ~0.4'x0.1', extending to the southwest of a mag 12.3 star. At its northeast end, close to the mag 12 star, is a very small "knot" (core of VV 267a = UGC 6073b, the face-on spiral) at most 10" diameter at the northeast end close to the mag 12 star [28" SW of the star].

24" (3/28/17): Arp 198 is an overlapping pair consisting of face-on spiral and a thin edge-on that extends right to the nucleus of the face-on. At 260x and 375x, the pair appeared as a very faint, fairly small, very elongated glow, ~0.4'x0.1', extending to the southwest of a mag 12.3 star. The faint glow had an unusual "spike" appearance, with a very small "knot" (core of VV 267a = UGC 6073b, the face-on spiral) at most 10" diameter at the northeast end close to the mag 12 star [28" SW of the star]. The spike or tail (VV 267b = UGC 6073a) extends southwest with the combined glow collinear with the star!

900/1200mm - 48" (5/1/19): at 545x; the bright edge-on in the overlapping pair Arp 198 = VV 267 appeared moderately bright, thin edge-on 6:1 SW-NE, 0.9'x0.15', very small brighter core. The slightly brighter core of the superimposed galaxy, VV 267a, was visible surrounded by a very faint halo. The view was improved by increasing the magnification to 813x. The core of the overlap was a fairly prominent round glow, surrounded by a faint but easy halo extending ~20" in diameter, nearly reaching the mag 12.3 star just off the NE tip.

48" (4/22/17): at 488x; the edge-on component (VV 267b) of Arp 198 appeared fairly faint, moderately large, edge-on SW-NE, ~45"x8", fairly low surface brightness with just a weak central brightening and no distinct core or nucleus. VV 267a = Arp 198 NED2 is attached on the northeast end forming a contiguous glow centered 50" SW of a mag 12 star that interferes with viewing.

48" (4/22/17): at 488x; the edge-on component (VV 267b) of overlapping Arp 198 appeared fairly faint, moderately large, edge-on 5:1 or 6:1 SW-NE, ~45"x8", fairly low surface brightness with just a weak central brightening and no distinct core or nucleus. VV 267a = Arp 198 NED2 is attached on the northeast end forming a contiguous glow centered 50" SW of a mag 12 star. The face-on (foreground) spiral component (VV 267a) appeared as a weak brightening at the northeast end of edge-on VV 267b. The core appeared slightly larger in diameter than the attached edge-on (~12" diameter) but the very low surface brightness halo was not seen, perhaps due to the glare from the 12th magnitude star less than 30" NE.
