wxEphe displays Astronomical Ephemeris for The Sun, The Moon, and solar system planets, given date and observer's location.
Starblinker is a supernova search tool. It allows you to easily search for new stars in your astronomical photos. If you find a new star in your image, keep in mind that it could be a defect in your photo, like a hot pixel, or: 1) An already known or a new unknown asteroid; 2) An already known or a new unknown comet; 3) An already known or a new unknown galactic nova; 4) If it is superimposed to an external galaxy, an already known or a new unknown supernova; Before reporting a potential new di
A planetarium software that renders a 3D simulation of the night sky. It can show star constellations, planets and nebulaes. It includes a catalogue of over 600000 objects.
SoundSteper is a software-only control tool for step motors used with telescopes. It works in real-time, operates over a sound card, and requires an analog sound amplifier, works with up to 4 moters in parallel; provides sync and go-to modes or joystick control even. It runs on Windows.
Nightfall is an astronomy application for science, education, and fun. It can produce animated views of eclipsing binary stars, calculate synthetic lightcurves and radial velocity curves, and eventually determine the best-fit model for a given set of observational data of an eclipsing binary star system. Nightfall comes with a user guide, and a set of observational data for several eclipsing binary star systems.
SkyChart draws an observable night sky of stars and nebulas from its catalog. It can also note the position planets, comets or asteroids. Many parameters allow automatic catalog selection, adapting colorization and dimensions, labels for non-star objects.
