Altitude and polar alignment


Recommended Posts

Hi can altitude affect polar alignment?

Just a thought experiment as I watch the snow fall here in Sussex.

If I'm on the beech at sea level and set up my alignment to Polaris at x° latitude and another day setup at the same latitude x° but I'm now at the top of a mountain surely Polaris would be slightly lower in the sky.

I can't believe my HEQ5 Synscan mount knows my altitude from my lat long coordinates.

Assuming a polar alignment has been done using the polar scope.

Any thoughts!

Polaris is reckoned to tb 434 light years away, Everest is 29,000 ft.

So the angular change is (9000 mtr)/(434 lightyears), you can convert it your self but you will need a calculator that goes down to a very small number

Angular change = 9000/((434)x(9.4605284 × 1015)) metres

At small angles you can approxomate Angle = Tan(Angle)

Looking at 2.2X 10-15
