bei 64x blitzt die Galaxie immer wieder westlich von einem schwachen Stern auf - sie kann mitunter auch gehalten werden und wirkt leicht länglich - bei 107x wirkt die Galaxie etwas flächiger, kann aber nicht mehr so gut gehalten werden wie bei 64x

The brighter galaxies (NGC7805 & NGC7806) were well separable. The faint MCG+05-01-026 is not visible with 8 inch aperture. NGC7806 is the middle one of the three galaxies.
NGC7805: Evenly bright, roundish. In comparison to NGC7806 slightly larger and brighter. Well visible with averted vision.
NGC7806: Roundish, fairly faint, rather at the limit of perception.

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.

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.

A rather difficult group for 4.5 inch. Transparent sky is very important. At 60x I saw a brightening, that includes NGC7318A/B and NGC7320. Separating them was difficult. Only at 100x I could separate both for sure and they appeared as oval nebulas.

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.
