At 37x the two brightest members (NGC3189 & NGC3193) are clearly evident. NGC3179 is very elongated and shows at 100x an elongated, distinctly brighter core area. Dust lane wasn't seen, but galaxy appeared more sharply defined SW. NGC3193 is round with very bright, compact core. NGC3185 appears at 37x as a relatively small, faint brightening, at 100x evenly bright and slightly oval. Most difficult is NGC3187: Only at third attempt I was able to see it. At 171x very faint, very elongated, thin, evenly bright. Barely held with averted vision.

At 100x NGC5353 appeared slightly oval with bright, distinct core, whereas NGC5354 appeared more roundish and evenly bright. Also well visible is NGC5350, which is largest member of the group. Already visible at 37x with averted vision as relatively large, roundish, rather faint brightening. At 100x the center was somewhat brighter. The much more fainter NGC5355 was well seen at 150x with averted vision as slightly elongated brightening. The faintest member is NGC5358: At 150x I could barely see this galaxy with averted vision as very compact, diffuse brightening, which was probably only the bright core area.

While NGC 7320 appeared rather uniform, NGC 7318A/B showed a slight increase in brightness towards the center.

Wonderful, but more fainter group near NGC7331. NGC7318A/B appeared at 80x as oval, evenly bright nebula with averted vision and is brightest member. At 214x I could separate the cores of both galaxies with averted vision. NGC7320 was also fairly easily seen at 80x with averted vision, oval, relatively faint. NGC7317 is located nearby a 13.4m star and appeared at 150x as a very compact brightening. NGC7319 is the faintest member in this group and was visible at 150x as an extremely faint glow.

Largest and brightest member is NGC7550, which was barely visible with direct vision at 96x. This galaxy appeared roundish with slightly brighter center, otherwise rather evenly bright. At 133x the core appeared very compact. Second brightest member is NGC7549, which appeared at 96x roundish, at 133x partly slightly oval. Overall quite faint, but well perceptible with averted vision. The slightly fainter NGC7547 was seen at 96x only as rather compact brightening, at 133x evenly bright. Probably I only saw the brighter core area. The two faintest members 7553 & 7558 I didn't tried until now.

Conditions in the target region: SQM-L 20.6
The level of difficulty is only related to the two brightest group members (NGC7578A/B). The other members might be too faint for 8 inch aperture. At 66x I could easily see with averted vision around NGC7578A/B a faint, evenly bright glow, which appeared slightly oval at higher magnification. At 171x I could fairly well see within this glow the two rather compact cores of NGC7578 A/B, which were clearly separated from each other. The core of NGC7578 B (northeastern of NGC7578 A) appeared a bit brighter and larger. I didn't looked for the other members of course, but the third brightest one (PGC70943) might be worth trying ;-)

This observation was a while back and I could only saw NGC7609 as very faint, roundish brightening, but at the limit of perception with averted vision. But don't expect too much from this Hickson/Arp group with 8 inch aperture.
