What is the best way to find an approximate bearing on a celestial body or conversely, to find a celestial body using a bearing? I've been doing it lately by simply facing forward in the direction of the sun/planet/moon after shooting a sextant sight and trying to be accurate using my trusty Silva hiking compass with sighting mirror. This has worked well in the past for getting rough estimates which I use as a check on my calculated azimuth. But I just recently purchased a Starfinder 2102-D and find that I might need a more accurate way to find a bearing in help locating the desired star. I'm thinking I'll just stand facing the general direction with the sextant set for the proper altitude of the body (according to 2102-D) and start scanning. But then this just seems somewhat inaccurate and dicey to me. Do I need a handbearing compass? It seems that any advantage of a handbearing compass would be obviated by the fact that it must be tilted up at an angle to get a truly accurate reading, and tilting compasses (in my experience) causes the card to become dampened, thus no actual bearing can be found. How is this done by other navigators, short of purchasing an astrocompass?

They are very logical, but you could never work out the rules, even if you spent all your time thinking about them. _________________________________________________________________ Express yourself instantly with MSN Messenger!
