Default Has anyone used a sextant to help with shots?

Has anyone used a sextant to measure ground angles of buildings and landscape features to determine when the Sun (or the photographer) would be in the best position for a shot?

They're pricey and would require artificial horizons on land, but I think that they could prove to be useful.

Cool

I have used this software for years. You employ a sextant to use it.

I liked one asset of the print out. You can trace the outline of obstructions like buildings, mountains or tree's so you know for a fact when the sun will be shining.

However, I believe there may be a smart phone app that will do the same thing without the print out and sextant. New school.

What brand and model of sextant do you use with the software?

Mark, I misspoke about this being a sextant. It is properly called a clinometer.

You don't take measurements directly from the sun or the stars with it. You take data from the software with which you match compass direction and the degrees up from the horizon. Then you see in the sky exactly where the sun was or will be.

Pricey though. $350 for software and this clinometer.

Agreed. It's easy to understand and accurate. It's been used to plan many a photo charter.
