Next Observation- https://www.youtube.com/watch?v=pDIPZ...Camera- Nikon P900 w/ homemade solar filter & my cellphone Date- 10/15/2017 & 10/16/2017ISS TRANSIT FINDER- http://transit-finder.com/ISS Angular size math- So lets over-simplify and utilize some right-triangles to figure this out. Now lets say my Camera had a tilt of about 45 degrees. This would mean that our line of sight would be the hypotenuse of our right triangle and would equal 354 miles. Now the angular size of the Sun is 0.53 degrees. Now lets see what the angular size of the ISS would be at 350 miles. Well the ISS is 350 feet on it's longest size. So at 350 miles, that would equal 0.0108 degrees. Now the sun is 1,240 pixels wide on my screen. The ISS is 24 pixels on my screen. So if 1,240 pixels = 0.53 degrees, that means 24 pixels = 0.0103 degrees. This means an error of only 4% from what we would expect. It's practically EXACTLY what we would expect for a craft that size at that distance.NOTE: Comments that make assertions w/ no evidence will get deleted. If you are going to foolishly claim that my observation is fake, you MUST back it up in your comment.
