Greetings Board Denizens:

I've posted here a little bit in the past and have always lurked on and off. Now (I think for the first time) I'm seeking a little advice.

To wit: The ephemeris in my old Celesticomp calculator is now finally obsolete, and it seems Celesticomp is dead, so I can't update it. Can anyone recommend a new celestial nav calculator to use???

I need it for the usual: back-up offshore nav, just in case, and the odd bits of recreational star, sun & moon shooting.

Many thanks!
