AstroGrav is a precision solar system simulator that calculates the gravitational interactions between all astronomical bodies, so that the motions of asteroids and comets are accurately simulated. The effects of general relativity are taken into account, and superb interactive 3D views allow you to easily rotate and zoom your view while the solar system evolves.

AstroPlanner is a stand-alone application that allows the user to plan and execute an observing session. The user can enter objects to be viewed manually, import them from text files, look them up in several supplied catalogues, or use observing plans previously created by others. These objects can be both deep-sky and solar system objects (planets, sun, moon, asteroids, comets, etc.).
Application IconOnce a list of objects has been created, they can be observed and log entries recorded for each of them. The application will also control a wide range of computerised Go To telescopes, in order to slew to selected objects. Several Digital Setting Circle (DSC) systems are also supported. Telescope control is optional, so AstroPlanner can be used to great effect even if you don’t have a computerised telescope mount.
The application computes the visibility of the objects for the current observing session, shows the sky for that time and can show the field-of-view for the current object as if it was being viewed through a virtual eyepiece, or the sensor of an imager.
Additionally, if you have a network connection, you can download high-resolution photographs of any part of the sky from the Digital Sky Survey (DSS and SDSS).

The free space simulation that lets you explore our universe in three dimensions.
Unlike most planetarium software, Celestia doesn't confine you to the surface of the Earth. You can travel throughout the solar system, to any of over 100,000 stars, or even beyond the galaxy.
All movement in Celestia is seamless; the exponential zoom feature lets you explore space across a huge range of scales, from galaxy clusters down to spacecraft only a few meters across. A 'point-and-goto' interface makes it simple to navigate through the universe to the object you want to visit.
Celestia is expandable. Celestia comes with a large catalog of stars, galaxies, planets, moons, asteroids, comets, and spacecraft. If that's not enough, you can download dozens of easy to install add-ons with more objects.

DashPhoon is a Mac OS X Dashboard widget that displays the phase of the Moon.
DashPhoon can either display the Moon as it appears now, or else at some other time. In the latter case, the display can be frozen at a particular time, adjusted by keystrokes, or advance rapidly by hours or days.

MoonMenu™ draws the current phase of the moon in the menubar. The menu, when selected, reveals the following information:
A textual description of the moon phase
The moon's age in days
Current lunation number
Farmers' Almanac names for the current lunation
Upcoming quarter predictions
Automatic "blue moon" detection that actually colors the moon blue
Sun rise/set times
Twilight rise/set times
Moon rise/set times

Nebulosity is designed to be a powerful, but simple to use capture and processing application. A huge array of cameras are supported for capture (see below) and images from just about anything can be processed (support for many FITS formats, PNG, TIFF, JPEG, DSLR RAW files, etc). Its goal is to suit people ranging from the novice imager who wants to create his or her first images to the advanced imager who wants a convenient, flexible capture application for use in the field. In it, you get a host of purpose-built, powerful tools to make the most out of your images and imaging sessions.
