Getting all the easy videos done first. From Shelter Bay observation #3. Same location as the last one, far dock at 5 km, close land about 1.1 km. Camera heights from 6 inches to 10 inches. The point of these repeat observations is to document a change in refraction conditions with time, over a short distance.

At some point I will make a video better explaining the ferry dimensions and far dock height, in case anyone wants to use these as evidence for a particular Earth shape. From these heights there would be less than a meter of the ferry (and ~2 high meter fairy dock) hidden at the far shore on a globe. The angle of visible water past the 1.1 km point is a better indicator of horizon (or inferior mirage) distance. It should be small on FE and almost undiscernible on GE with standard refraction, especially with the later wider FOV.

$Refraction Rainbow! Sort of.$ $High Treefraction Time Lapse (4K)$ $12 km Observation - Camera Movement has me Stumped! First observation from this location for the season. The water level needs to be high enough that Im not looking over miles of beach. Bizarre weather this season making it very difficult to do observations or much of anything really. More on the weather and details from this location in the next video. A short, wider angle time lapse from 6 feet followed by a few hours of footage from 5 inches. Trying to use a closer foreground object (old uprooted stump) as a reference to detect full frame camera movement. Low camera set up on a rock and shouldnt have gradually moved, but there was some noticable movement of the frame anyway. Very distorted refraction and hard to see all day even with some cloud cover. Still remained a black swan the entire sequence with no obstruction below eye level. Thoughts?$

$1 Hour of Raw Footage from 12 KM Observation Point #7 This is the last hour of a six hour observation on October 15th. This was distance offset optical test attempt 4 of 5, so far. I only edited out a few minutes here and there, and removed the audio for now. Ill eventually make a shorter video of the highlights, along with some thoughts on what I think is causing the later mirage effects. This was the most active refraction portion of the observation. There was a good range of inferior mirage/obstruction, which gradually transitioned to this final mix of inferior mirage and looming. Ill eventually put more detailed info in the comments, along with timestamps of interesting events.$

$Flat vs. Concave (Black Swan Comparison) This is a rough comparison of an observation against a flat geometric prediction. There is no comparison to a convex surface globe model in this video. In this case we are measuring upward displacement caused by downward refraction over an assumed flat plane water surface, and the apparent height limit that this effect was occurring. This is a typical black swan observation, where the water surface appears concave (rising up with distance) from lower elevations. There is considerable compression, miraging and distortion, but no obstruction. Nothing can be obstructed above eye level, although targets can be compressed and visually obscured beyond recognition. Ive been working on this video off and on since March 19th (Shelter Bay observation #3) and I keep going back to make things more accurate as I confirm heights and remeasure everything. Still, I cant guarantee the accuracy of this analysis. Its a good starting point and Im confident that everything is close, but Im also open to any suggestions for getting more accurate results. At some point Ill provide a more detailed look at how I determined the rough heights of everything.$
