Making Celestial Navigation Easy!

EZ Celestial LLC has been making celestial navigation easy since 2011. Our flagship products ezSights, ezAlmanac, and ezLunars have been revolutionary in both performing celestial navigation and teaching it as it has been done for 100's of years.  Our latest product, ezAlmanacOne, combines the best features of ezSights and ezAlmanac into a single product with a modern user interface designed to work on all screen sizes and platforms.

DESIGNED FOR  
USE AT SEA

EZ Celestial software is fully functional with no network data connection.  Astronomical calculations and table generation are performed internally using the NOVAS 3.1 vector astronomy software from the USNO and a JPL ephemeris covering the years 1960-2059.  For the compass check functions, ezAlmanacOne computes magnetic declination for the current location using WMM 2020, the latest world magnetic model provided by  NOAA.

ezAlmanacOne

Perform celestial naviagtion exactly as it has been done for 100's of years and exactly as it is taught in celestial navigation courses. ezAlmanacOne will do all of the work for you and teach you how to do it manually by example. You can generate and print all of the tables needed  to manually find your fix without the app when you are ready to do so.

ezLunars

Learn to do lunars as they were done when the pre-computed lunar distance tables were published in the Nautical Almanac over 100 years ago (last published by the USNO in 1906). ezLunars will do all the work for you, teaching you the process.  All tables can be printed for use outside the app when you are ready to do it manually.

Cel Nav Books

We think "Practical Navigation" if one of the best books ever written for celestial navigation and we are proud to offer it as a resource to our app users.  Paperback and digital Nautical Almanacs are also available, as well as a book of solutions for  the problems presented in the book “100 Problems in Celestial Navigation” by Leonard Gray.
