DSO is a freeware astronomical program for Palm OS devices that should help to plan observations of deep sky objects.
The program allows to search for objects in the NGC/IC database by the object:

Daily Astronomy Data 2011 Win Mobile - Jim Edwards had an annual ritual. Every year he would read magazine articles about the up-coming Orionids meteor shower. The trouble was, he always seem to read about them after-the-fact! Jim consistently missed one of nature`s finest celestial displays
Jim is not alone
Astromist (Palm OS) - Astronomy tool to easily locate and compute position of stars (up to 2.5 million),planets or sky objects (18200 included) of most well known catalogs
It provides powerfull sky chart to easily find objects, Hipparchos and Tycho stellar catalog, objects photos, moon phases calendar to plan your observation session, many sky objects (more than 18200)
AI (Astro Info)- 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
Planets is an educational document with which you can start to learn about the physical characteristics of the different planets in our solar system.
The program includes 3D models with realistic textures based on the surfaces of the planets, and a wide variety of information such as: distance from the sun, diameter, mass, atmospheric composition, surface matter and more
2004 Meteor Shower Database - This is a database of 2004 meteor showers, including: name of the shower, date range, date at which the shower peaks, the maximum rate per hour, and the radiant.
For observation, the higher ZHR (Zenithal Hourly Rate), the better (more meteors).
Maximum dates in parentheses indicate reference dates for the radiant, not true maxima
2005 Meteor Shower Database - This is a database of 2005 meteor showers, including: name of the shower, date range, date at which the shower peaks, the maximum rate per hour, the entry velocity, and the radiant.
For observation, the higher ZHR (Zenithal Hourly Rate), the better (more meteors)
astrolib - The astrolib library calculates planetary positions and timezones.
Positions of sun, moon and planets up to Pluto are calculated with an accuracy of the order of one arc minute for dates less than a century away from now. Calculations are based on approximation formulae by Paul Schlyter, which are in turn based on a preprint of a paper by T. van Flandern and K
