Robert Zebahl
63mm f/13.3, 46x, Bortle 6-, SQM-L 19.0
Clearly split, but tight with noticeable difference in brightness.
70mm f/5.7, 80x
At 67x pretty tight pair, but separated with a clear difference in brightness. The primary component appeared in a hint of orange. At 80x easy to separate.
8" f/6, 100x, Bortle 4, NELM 5m.9+, SQM-L 21.0

B 8x44
AB: 2020-11-25: Easy to split at still quite small separation and visible difference in brightness. The primary component appeared white-yellowish, the companion darker.
B 12x42, Bortle 4-, SQM-L 20.8
AB: 2022-10-19: Easy to split at moderate separation and small difference in brightness. Well visible color difference, although it is difficult to assign the color to the components: white-bluish & yellow-orange.
70mm f/5.7, 22x
AB: At 22x widely separated, striking with a rather small difference in brightness. A seemed a bit warmer in color compared to B with a hint of orange. At 44x, both seemed slightly orange with very little difference in color.

The bright NGC772 was already evident at 37x, oval with much brighter center and visible with direct vision. At 80x also the fainter companion NGC770 was well visible with averted vision as quite compact, roundish brightening.
NGC772 appeared in a 10 inch Dobsonian slightly drop-shaped.

Robert Zebahl
8" f/6, 96x, Bortle 4, SQM-L 21.0
Conditions in the target region: SQM-L 20.9
I only saw NGC935 for sure: At 96x obviously oval, center seemed to be somewhat brighter, otherwise rather evenly bright. At 171x I could saw a stellar brightening within the halo. Probably this was the 14.27m foreground star southeast of the core. The axial ratio was about 1:2 to 1:3. IC1801 wasn't clearly visible to me.
Even under better conditions (Bortle 3-, SQM-L at the zenith 21.3) IC1801 was not visible at 171x. 		MODERATE

At 96x obviously oval, center seemed to be somewhat brighter, otherwise rather evenly bright. At 171x I could saw a stellar brightening within the halo. Probably this was the 14.27m foreground star southeast of the core. The axial ratio was about 1:2 to 1:3. IC1801 wasn't clearly visible to me. 		MODERATE
