I think it is wonderfully you guys can navagate so accurately you can go over the Seas or land three thousand miles and pull up to a fence three barbs from the next post. For me unless it is for a science project I would be more than sastifed to use my sextant to be with in a couple miles of just the fence and have injured all the beautiful sites along the way realtor than have my nose in lookups from morning till night. Guess it is just what your purpose of Celestial Navigation is.

Celestial friends,
Thanks for the info. Just one formula.
I know now I only have to remember
Hc=arcSin(Cos Ldt+Sin Ld) (ik write then of course CosLdt is Cos L•Cos d•Cos t etc.)
if L and d are contrary use -dHermanD
