Bobby Shafto | Canigo in IR Addendum @bobshafto | Uploaded September 2021 | Updated October 2024, 5 hours ago.
This is a follow-up to my previous video requesting input/feedback and where viewers believe "eye level" - a common term for horizontal, 0 degree, line of sight -- was in the image presented here: youtube.com/watch?v=t8j67p4og0M
This addendum is mainly in reply to a request by Heath Carmody for some angular reference, but it may be of interest to others.
The gridlines in the 2nd half of this short montage are 0.5 degree apart. What I'm searching for is how to orient the grid such that 0 degrees horizontal (aka "eye level") is in the correct, predicted position. I anticipate the answer will vary, dependent on whether one believes the earth is flat or if the earth his convex like that of a globe earth.
All images were shot by Bruno Carrias from Le Croix de Provence in 1000nm near-infrared, with the resulting image assembled from stacked shots. Each image was from a different day, under different conditions.
I used the near coastal ridgeline and smokestacks to anchor the images. You'll see Canigo and the apparent horizon fluctuate vertically under varying atmospheric conditions.
