Celestial is a complete package for celestial navigation on your Android device. It can perform celestial sight reductions, calculate fixes, present them visually, manage sights on multiple trips and assist in sight planning. It also includes a complete Almanac of the Sun, Moon, planets and stars. All this for less than the price of the Nautical Almanac for a single year!

In detail:
- Supports quick sight reduction. Enter all sight values to quickly calculate an intercept or to double-check your own manual sight reduction.
- Includes a comprehensive trip manager that allows you to manage sights taken during a trip. Keep your sights with you forever!
- Multiple sights can be grouped and averaged together and a fix can be calculated. Lines of Position (LOP's) and fixes can be plotted on a virtual plotting sheet.
- Running fixes are supported!
- Includes a star finder and times of rise/set phenomena. Plan your sights and be on deck when it is time.
- Includes the complete Almanac of the Sun, Moon, planets, 57 navigational stars, Aries and Polaris for the years 1980-2099.
- Context-sensitive screen help for every screen so you always know what the intended function of the software is.

All sight reduction algorithms are based on the algorithms described in the Nautical Almanac (Sight Reduction Procedures). Celestial object positions are predicted using software from the US Naval Observatory.

    Really cool. Does everything you need for celestial except take the sights. Only thing I would like to see added is zoom for the plot.

    What a great piece of software. Having written a sight reduction program in Basic in the 70s I really appreciate the ease of use of this app. It takes away most of the tedium between taking a series of sights and getting a fix. I look forward to once agai

    "Five stars when it starts working again." This is now! Great app for navigation. Verified on ICS and JB. Thanks, Navimatics!

    Could be a little more user friendly. Might consider a light (red) for reading sextant. Distance from gps position would be useful for beginners to gauge their accuracy.

    All you need is a sextant and your ready to go. I would like to see SD card support. Atmosphere in inches of mercury and temperature in fahrenheit.

    Great App, but why not throw away the sextant and use the camera from the PDA to do the sighing of the sun? Time and elevation are already available in the phone.
