Zvi,
My suite:
http://www.navigation-spreadsheets.com/
may not exactly fit your criteria but on the other hand you get plenty of sight-reduction tools as well. Once you download the suite, you can use these tools even without access to the Internet. Furthermore, the spreadsheets are not tied to any particular computer platform; as long as you have an Excel-compatible app on your machine, you can use them whether your machine runs on Windows, Mac, GNU/Linux, iOS (iPhone, iPad), Android, whatever... :-)

Hello.
The UK Nautical Almanac Office produces a 96 page book called Compact Data
for Navigators and Astronomers which covers a 5 year period (2011-2015) and
provides constants with which the GHA and Declination of the Sun, Moon, planets
and stars (Aries presumably) can be calculated with a pocket calculator or a
slide rule. Unfortunately they package this with a piece of navigation software
called NavPac and the combined price is anywhere from £60-£72. They do not sell
the book with the tables on its own.
Does anyone know if there is a similar but cheaper paper only product made
by someone else, or alternatively if this compact data is available on the web
in some form? I am not talking about websites that calculate GHA and Dec for a
given date and time – just the compact data with which one can calculate them by
oneself.
