Capt. Gilbert Rude invented the star finder in 1920. The star finder allows for sight planning so that a round of stars can be efficiently performed during the brief twilight period. The sextant is pre-set to the approximate altitude so that a star will be seen through the sextant optic when held to the horizon in the general azimuth direction. An unidentified star can be observed then identified later during sight reduction using the star finder.

Make sure you double check the color paper. I accidentally ordered ivory parchment but wanted the navy pictured. That was my own fair, but be sure to double check.

This was a custom order for my family. Very special. Quality research and job printing. Well packed Fast ship. Very pleased to have found Blue Moon. Great transaction! Have a blessed week! :-)
