Arp 324, SDSS
Arp 324, UGC 10143 chain, VV 159. In Abell 2147. Her. Galaxy chain. Stretches across the 100 deg. field in 5.5 mm. W of a bright star. S-most member, nearest to the star (VV 159f) strongly elongated E-W, well defined. Next one to the N, VV 159c (MCG+3-4-51) is one of the two most prominent ones. It is round, with diffuse edges, and concentrated to the center. Component "d" is a small glow just E of a faint star. It is distinctly nonstellar and extended roughly NS (photographically, it is two starlike objects nearly in contact - III Zw 75). Component "b" to the N in the chain is a weaker version of "c". Star to the W has a threshold companion to its NE, which appears large and diffuse. VV 159e is difficult but can be glimpsed SSE of a star in the chain, S of "a" (UGC 10143). The latter, alongside "c", is one of the two most prominent galaxies in the chain. It is slightly elongated NS, and has diffuse edges and bright center. Sketch
Arp 328, SDSS
Arp 328, Hickson 72, VV 165, galaxy chain. Boo. 5.5 mm. Immediately noticeable as a group elongated NS to the W of a star; very bright star on edge of field. Hickson's "A" is a solitary companion N of the compact chain and S of a star. It is slightly elongated NW-SE. Component "B" on the N end of the compact chain is slightly elongated NS. It is almost touching "D" to the SE, which is extended NNW-SSE. Component "C" to the S is slightly extended NW-SE and is larger that either of the last two. Star to its SE is difficult and VV 165g between them is invisible. Then, after a while, in better clarity, the star, the small and faint "g", the star [actually, PGC 52847] NW of "C", and the similarly small and faint "E" to its NE are all seen quite well. Sketch
Abell 70, DSS
Abell 70, PN in Aql. 5.5 mm. Without filter, the elongated galaxy on N edge dominates. There is only a suggestion of a nebulous arc completing the circle with the galaxy. Bright star E, double star N. With OIII filter, the planetary is a more definite annulus, and the galaxy is hardly noticeable (perhaps just the compact core or a knot in W end). Sketch
