Yes. I use TPE. It manages all about sun/moon, etc. But it's all from above, you know. I need something to compute from my shoes with camera on tripod and in location. I have a compass here. since the azimuth represents the degree of the area where the sun rise in relation to the north, and how many degrees will have when it will fall, if I'm remembering right, I guess, since I know the azimuth degree where the sun will fall, so a compass should point exactly to that direction if it has degrees. But my compass is just one of 1 dollar. It doesn't have any degrees, just lines. i believe that I can calculate, with accuracy, the position where the sun will fall by using a compass, but I don't know any professional compass, so I cannot be sure if what I'm thinking matches the reality.
I'm pretty new at land/water photography, so I'm probably missing something.
This is TPE (planning a shot for tomorrow):
