Time lapse video of night scene with camera rotating to stabilize frame with respect to stars.
Bendy light, dome refraction, atmospheric effects or other phenomena postulated to occur at or near the horizon have little to no observable effect on perceived line-of-sight to stars shown.
You beat me to it
! I was going to post a similar video but more to show how the Earth appears to rotate compared to the "fixed" stars.
Any effect of refraction (bendy light) is only within a few degrees of the horizon.
I doubt that the mountains allow the stars to get close enough to the unobscured horizon (ie 90° from the zenith) to see any refraction.
But Flat Earthers like Tom Bishop propose light bending magically by 20° or more to make sunrises, sunsets, Moon phases etc fit exactly what we expect on the Globe.
For entertaining reading have a look at
Electromagnetic Acceleration.
Is that what they mean by
Zetetic Science ?
