Hello Don
The sun has an angular diameter of about .529447 degrees so the solar angle can vary by ± .2647223 degrees and still be in line of sight range. If that helps?
I did see some of your connections but I’m a little hesitant making connection with a satellite photo! My main focus was to connect Giza with the solar and stellar angles.
Also I’m still doing research but thanks for your input its much appreciated!
I’m thinking the basic idea behind this next image may work out to be correct but still too early to know for sure.
Opinions on this would be helpful !!!
