    Paul,

    Take a look at this article by David Berson of Ocean Navigator magazine, published on Dec. 2, 2015:  http://www.oceannavigator.com/Web-Exclusives-2015/Navigating-with-a-celestial-computer/

    He says:
    A tool like my Celesticomp — and I have three of them by the way, including a backup and a backup for the backup — has a permanent nautical almanac for the sun, moon, and the other planets and 173 stars, and has all kinds of bells and whistles to calculate great circle courses, rhumb line, course over ground, etc. It will calculate your time for morning twilights, nautical twilights and civil twilights, and can update the DR automatically.

    Note the word "permanent".  Other articles, some about older versions of Celesticomp, use the work "perpetual".

    I could not find anything about how "permanent" the almanac is in the Celesticomp manual I found on the web.  Does your manual give any hint?

    Stan

    I have Celesticomp v No. 17030658 5/11/92. Is the ephemeris out of date ?
