Description
Functional sextant with vernier scale precision of 6' (6 geographical minutes).
For sun protection shields I used a standard spare glasses for welding mask.
Mounting screws are M3 and for sun shields M4.
I used 3mm glass mirrors, but they are not the best because of light refraction error in glass. Better would be mirror made from polished steel it gives almost no refraction error.
Sextant frame i made in two elements because not enough space on 3D printer table.
