NavList:

I think the top of the diagram should be labeled "North Pole". I'm interested in how you generate diagrams like that on a computer. I'm not very computer savvy, but I have sons that can help me learn. Since I think that I understand the Direct Triangle solution of the LDc, I would like to make  a folder of illustrations of the process. I envision beginning with an altitude/azimuth view of the sky to the south that shows the sun in the SE and the moon in the SW at a specific time (about 3rs quarter). The positions of the sun and moon would be indicated by open circles on their respective azimuths and the observed LD would be shown as the distance between their near limbs. The next illustration would show the LDpc distance obtained by adding the SDm(aug) and SDs. The next illustration would show the altitudes of the bodies (and maybe deal with HOE if altitudes were obtained with a sextant), etc. Anyway, that is what I'm attempting to do.

I looked a little further into the Navigational Stars plugin on Stellarium and I now see such things as GHA  Aries, etc., that I remember you mentioning. Thanks.
