HCSP Celestial Navigation Cruise

GPS Track for 8 and 9 August 2015

Just back home after a 2 day overnight cruise on Lake Ontario in order to take some sextant sights to practice some Celestial Navigation with a proper horizon after getting out into the middle of the lake.

Accuracy of the shots needs some work - after working up the sight reductions and plotting the 9 Aug 2015 position against the GPS, it showed a significant error in comparison. Will have to do some more sight practice to get more accurate.
