Finally got my first proper lunar distance attempt, after about a year of self-teaching and then waiting through the winter for decent observing temperatures. Stepped outside onto the porch to get fresh air as we were sitting at the table after supper last night, and then just couldn't resist Jupiter. Got out the sextant and took three shots of the lunar distance. One of our guests was a curious boater who wanted to look through the sextant anyway, thankfully. L 46d 16.6' N Lo 63d 10.8' W GMT 23h 55m 18s IC = -0.2' T = 49 F BP = 30.4" Sextant angle = 71d 13.8' Frank's online calculator result: Cleared LD = 70d 55.3' Error in Lunar = 0.2' Error in Lo = 0d 06.3'. Very cool. Now I see how it works. Jim
