It is not from last night, but from a few years ago. For possible interest I include the report.
Location: mountain pass at 1700 m (5600 ft)
Sqm-L at zenith: 21.3- 21.5.
Instrument: Newtonian 6" (Skywatcher 150P) on a Omegon Twinmaster mount.
Binoviewer: Linear (Omegon)
Eyepieces: APM UFF 18 (42x; 1.3⁰) and Super Plossl Omegon 15 mm (50x; 1⁰).
Time: mid-February.
I observe the Auriga and Gemini clusters. The big ones look fantastic. Of the small ones, NGC 2158 is extensive but it does not resolve any stars (in bino). NGC 1907 looks smaller, but I do see a handful of faint stars.
M 31 and M 33 are a little low, but I can see, in addition to the two satellites, the first dust line in M31 and NGC 604 and the arm that leads to it (I'm not sure I can see the other arm) in M33.
M42 is spectacular. I remove the binoviewer and I see the same extension of nebula, although a little brighter. The flame is practically the same in bino and mono mode. I don't see the horse head in any way.
I take a look at Eskimo (without filter) and it looks small and lack of details, of course, but with greater extension than from the city.
Something happened with M1 that caught my attention. In bino mode I noticed a bit of mottling, which in mono mode disappeared. This reinforced my choice and I was happy to see in situ the effect of observing with two eyes.
I observed a lot of galaxies. Although with such a small aperture and low magnification, I could detect only the cores, some halos (in the brightest ones) and shape notes, binocular vision seems to me to enrich this type of observation.
M 81, 82, NGC 3077, 2976, 2683, 2841, 2903, 3227, 4565, 6207, sombrero...
That night I saw stars of m. 12.3 with the binoviewer and 13.3 in mono mode.
