UGC 934: bei 206x blinkt ein kompakter, schwacher Schimmer auf, der schwache Stern nordwestlich ist auch nur indirekt zu sehen - bei 288x ist der schwache Stern direkt sichtbar und der Schimmer UGC 934 kann länger gehalten werden - keine Form oder ähnliches erkennbar
PGC 212740: der kleine, schwache Begleiter südlich von UGC 934 ist allen Vergrößerungen bis 288x nicht auffindbar

Arp 157 (Gx)

Arp157 also contains the faint galaxy UGC957, but NGC520 is much more interesting. UGC957 (b18.0m, 1.2x0.9') is located NNW of NGC520 and north of a fainter field star (see DSS image).

Conditions in the target region: SQM-L 20.6
At 66x evenly bright, elongated, evident with averted vision. At 133x slight broadening toward the south end. The very faint extensions and the dark lane were not visible.

Oval, evenly bright. At 133x better visible, but still almost evenly bright. I guess, that I only saw the brighter central area.

The eastern NGC474 already shows impressively concentric rings. On long time exposures very complex structures came to the fore.

NGC470: Already visible at 66x with direct vision. At 100x oval, slightly brighter core, otherwise evenly bright.
NGC474: Already visible at 66x with direct vision. At 100x roundish, appeared smaller than NGC470, but similarly bright with relatively bright, distinct, compact center.

NGC379: Already seen at 80x as small brightening. 200x: oval shape.
NGC380: Barely seen at 80x as small nebular with averted vision. 200x: round shape.
NGC383: Brightest member. At 80x round with slightly brighter core. Well visible with averted vision.
NGC384: Very small, compact. Intermittently seen with averted vision. It took a while to see this faint galaxy. Already glimpsed while observing nearby NGC385.
NGC385: Small, compact. Intermittently seen with averted vision. A bit brighter than NGC384.
