Free magnitude software for pda

The GeomagInfo is an application for Ewe enabled computers to compute the magnetic declination, inclination, and magnitude for any location on Earth.

Its main use is to give the current magnetic declination to correct a magnetic compass. This application is most useful for those hiking and traveling without topographic maps in unfamiliar territory. A magnetic compass can be off by many 10s of degrees in parts of the world. This application is also useful for correcting the magnetic declination of old topographic maps and navigation charts.

This is the latest release of our FREE open source astronomical ephemeris.
AI (Astro Info) provides comprehensive data on objects in our solar system as well as catalogues of all types of interstellar objects.

This makes AI an invaluable tool for planning and observing with handy features such as showing objects currently above the horizon.

This release includes:

Improved colour graphics
Object details including rise/transit/set, phase, distance, magnitude and position in multiple coordinate systems
Graphically show phase of our moon and solar system planets using real images or drawings (see screen shot above)
Major overhaul of the user interface
Sky map with ability to zoom and change limiting magnitude
F-A-S-T and accurate maths using combination of virtual floating point library and Meeus calculations
Change viewing date and time from any form
Show time as julian date and sidereal time
Rise/set time for all planets in our solar system in one form
Only 78KB of memory without optional catalogues
Your choice of catalogues containing thousands of objects including:
Messier
Caldwell
Bennett
Yale
SAA 100 (best 100 non Messier objects from sci.astro.amateur newsgroup)
Revised NGC/IC catalogue - this is the most accurate version of this catalogue available! Coming in V3
Optional night mode (red) for colour devices
