WebDec 13, 2024 · The horizontal line of sight may be determined by visual horizon information or by gravitational information (e.g. vestibular and proprioceptive feedback from the body). There is also evidence that when there is no ‘true’ visual horizon (as in a room where there is not an infinite ground plane), the floor-wall boundary serves as the visual ...

I imagine exactly the same restrictions apply to imaging, although long exposures would probably exacerbate the problem of skyglow near the horizon. flag with a sun and blue stripes
What is your minimum elevation (above horizon) for imaging?
From a point above Earth's surface, the horizon appears slightly convex; it is a circular arc. The following formula expresses the basic geometrical relationship between this visual curvature , the altitude , and Earth's radius : The curvature is the reciprocal of the curvature angular radius in radians. A curvature of 1.0 appears as a circle of an angular radius of 57.3° correspondin… WebHigh visual horizon (HVH) is a practice that far too many drivers do not employ. HVH is … WebAdvanced Driving.
