A planetarium software that renders a 3D simulation of the night sky. * default catalogue of over 600,000 stars * extra catalogues with more than 177 million stars * default catalogue of over 80,000 deep-sky objects * extra catalogue with more than 1 million deep-sky objects * asterisms and illustrations of the constellations * constellations for 20+ different cultures * images of nebulae (full Messier catalogue) * realistic Milky Way * very realistic atmosphere, sunrise and sunset * the plane
Gaia Sky is a real-time 3D Universe application that runs on Linux, Windows and macOS. It is developed within the framework of ESA's Gaia mission to chart more than 1 billion stars. A part of Gaia Sky is described in the paper Gaia Sky: Navigating the Gaia Catalog.
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
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.
