Hello everybody. Found the forum through several google searches looking for info on sextants. Im an airplane and sailplane pilot, after reading Guy Murchie's Song of the Sky and Bob Buck's North Star Over my ShoulderI've got a real fascination with learning celestial nav. I know where to get the tables and other books that I need but I'm looking for some advice on where to get a sextant. I'd obviously like to have one with a bubble level so I could use it in flight. I also really don't want to break the bank as this is more of a curiosity than anything. I have seen many posts warning against getting a plastic sexant due to warping issues. However I'm wondering if anyone produces a plastic sextant with a bubble level as that would be a cheaper way for me to get started and then see if I like it enough to go for the higher dollar equipment. Any advice/suggestions is appreciated. Thanks!
