Oh wow but that makes sense.
Huh is there a good approach to that then besides mosaicing?

Great shot Bernd!

And evidently I was tired when I wrote the first post.
I meant to say "high in the November evening sky" in the constellation Taurus, visible all night from dusk to dawn.

Pleiades Mosaic (2025 edition) - AstroBin
This two-panel mosaic integrates 3 imaging sessions in 2024 and 4 imaging sessions in 2025, filtering down to my best 540 × 120” on each panel. I tried to edit reduce star bloat and bring out the whis...

I suppose the counterargument is that scientists aren't charged with a crime for advising a Chinese student 5 years ago, and merely made unfundable / unemployable?

Since odds were low I didn't put much work in. Walked a few minutes from my house in SE Bloomington near Jackson Creek area.
Haven't tied Owen County but nice idea!

Whereas photo above is ISO 1600, 1", trying desperately to pick up that pillar against the golden light pollution-illuminated clouds. (Based on direction, that looks to be Indianapolis lighting up the clouds.)

Yeah, definitely working my ISO back down now. I picked up (bad) habits in earlier Kp4 auroras that really take much different settings. (You're just trying to pick up that faint signal, but with fast enough exposures to get some structure.)

Indeed!
And the prior night I was in overexhausted mode and didn't think things through to get a decent photo. It was *so strong* that my typical ~1" exposures at ISO 3200-6400 were just solid red. (Sigma Art 24mm f/1.4)
I *should* have reduced to 0.25-0.5 sec to try to bring out some structure.
