Very bright Hickson group. Worthwhile!

Only the two brightest members were visible. Both fairly well seen with averted vision. NGC3193 appeared roundish with brighter core, NGC3189 very elongated and nearly evenly bright, whereas only the brighter core was visible.

The two brightest members were apparent with averted vision: NGC3193 appeared roundish with brighter core, NGC3189 very elongated with also elongated, brighter core and fainter, diffuse outer region. NGC3185 perceptible with averted vision as fairly faint, roundish, evenly bright nebula.

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.

NGC 3185: bei 144x unscheinbar, aber gut direkt erkennbar und homogen hell - indirekt leicht heller und etwas diffus - bei 240x wirkt die Galaxie indirekt etwas fleckig

NGC 3187: bei 144x indirekt als ganz zarter Nebelschimmer erkennbar - kann auch länger gehalten werden

NGC 3189: bei 144x größer und heller als die nordöstlich stehende NGC 3193, leicht längliches Zentrum

NGC 3193: bei 144x südlich von einem Stern zu erkennen, kompakt mit hellem Zentrum

Conditions in the target region: SQM-L 21.0

NGC3746: Roundish (?), faint. Brighter and larger than NGC3748.

NGC3748: Faint, roundish, pretty small.

NGC3750: Located southwest of NGC3753. Difficult to separate from brighter NGC3753. Just visible as very faint, roundish brightening. Held with averted vision.

NGC3751: Most southern member of the group. Unfortunately for some reason I didn't tried this one.

NGC3753: Slightly elongated, rather evenly bright, pretty faint. Brightest and largest member of the group.

NGC3754: Northeast close to NGC3753. At 220x & 220x absolutely nothing was seen.

MODERATE

Conditions in the target region: SQM-L 21.0

NGC3745: Round, compact brightening. Anything but evident at 225x.

NGC3746: Evident, slightly oval, getting a bit brighter towards the middle. Still visible with direct vision.

NGC3748: Small, round brightening. Well seen with averted vision.

NGC3750: Roundish, condensed brightening. Almost visible with direct vision.

NGC3751: Most southern member of the group. Unfortunately for some reason I didn't tried this one.

NGC3753: Obviously oval/slightly elongated, getting brighter towards the middle. Still visible with direct vision.

NGC3754: Ziemlich schwache, rundliche Aufhellung dicht an NGC3753.
