Had a little bit of time to do some research on this while understanding one of the math disciplines that will provide the answer I need, Geometry. Now, while I didn't take trigonometry in high school, I did take Geometry. I need the hypotenuse angle for a right triangle. Knowing the length of A and B, the angle of the hypotenuse can be calculated. And that is what I am needing. Phewwy to Trig!

7' wall, distance from wall 10' = hypotenuse Angle = 34.99. If you want a horizon at about 30 degrees, the distance from a 7 wall would be about 12 feet. Now this is measured from farthest point from the wall, so you have the added flexibility of being able to move the mount closer to the wall as you increase its height. The height of mounts in the example below is estimated at the halfway point of the ground leg of the right triangle.
35-degree horizon at 5 feet from any wall, minimum height of mount = 42"
30-degree horizon at 6 feet from any wall, height of mount = 42"
Minimum height of EQ6-R on pier tripod = 49"
20x20 pad, 20x15 building. Northern, wall 20'
obsy room 15x15, warm room 5x15, outdoor pad, 5x20
Mount #1 = 5' from eastern wall, 6' from Northern wall
Mount #2 = 5' from western wall, 6' from Northern wall
Distance separating mounts = 5'
Mount 1 and 2 = 9' from Southern wall, (Plenty of room to set up chairs in the obsy room.)
Looking at this, I see the roof sliding off to the East.
Comments, suggestions welcome, please!
Clear Skies,
Chris
