Hey everyone, I have a possibly off topic question to ask. I have the possibility of posessing my late Grandfather's sextant from when he was an ocean going ship captain. Only thing, if I have it I want to know how to operate it. Obviously, with LORAN and GPS, sextant knowledge is not very important any more. Does anybody know where I could learn about using a sextant, doing sun or star shots, etc??? I would love to learn this part of history, although I know that I will never really use these skills as they once were used. Any help would be great. TIA, Jim Proud to be an American, Jim Hann Waterski J-41 Captain STL
