What we are trying to solve for is not the GHA of Aries but the local hour angle LHA of Aries and we do this by using the method of subtracting our assumed longitude from the GHA if we are in west longitude. If we are in east longitude, we add these numbers. Okay, take a breath. The Rude Star Finder is a collection of clear two-sided plastic discs that go from 5 degrees to 85 degrees at degree increments.
These discs sit on a white plastic two-sided centerpiece, also labeled North and South, that has stars positioned in place on it and an outside scale running its circumference that represents the local angle of Aries. In the northern latitudes, we use the sides that are labeled North. In this case, we find the North 45 degrees plastic disc and place it on the star disc.
It is held in place with a plastic pin.
Now, to find the available stars for our local area, rotate the disc on the white plastic disc until the hour corresponding to the LHA on the inner white scale — in this case, 95 degrees. Now we can find the true bearing and altitude of the local stars. We want good cuts, so we look for at least three stars that are more than 45 degrees apart.
Remember: it is better to shoot three stars four times than 10 stars once. At twilight, in order to find the stars, you look over the compass, factor in the variation to get true course, set your sextant angle at approximately the right altitude, look out toward the horizon and — whammo! Now there are other methods of finding available stars, most notably using Volume I, HO Meanwhile, I am off to sea on a trip to Bermuda and I will let you know, if I get back, how it all worked out.
