Open Source Astronomy Software

The EQ mounts' internal electronics provides pointing accuracy to .144 arcsecs. EQMOD connects the EQ directly to a serial comms. This project has the source files for the Public releases of the EQMOD ASCOM driver, associated programs and an EQMOD compatible hardware design. Please note that later test releases for all EQMOD Project software may be available via the EQMOD Yahoo group.

Echoes it's a radio spectral analysis software for SDR devices, designed for meteor scattering purposes. The older releases supported only RTL-SDR devices. They are very cheap SDR based on DVB-T TV tuner dongles based on Realtek's RTL2832U chipset. Starting from 0.50 Echoes embeds SoapySDR allowing the support of many other SDRs. Echoes doesn't demodulate neither decode any human-made signal. Its main goal is to analyze and record the total power of natural signals and generate screenshots and tabular data (CSV,) output in presence of particular peaks in a selected narrow range of frequencies. Since there is no demodulation, there is no provision for audio listening, except for a notify sound when an event has been recorded. Finally, Echoes can also operate getting an audio input, thus producing audio spectra. This way, Echoes can also be used with traditional receivers.

As of 2020, this project has moved. See https://mesastar.org. Release versions can be found on Zenodo at https://doi.org/10.5281/zenodo.2602941. The code is now hosted on GitHub at https://github.com/MESAHub/mesa. You can find the documentation at https://docs.mesastar.org/.

Astrology software inspired by the SYMBOLON deck. This software calculates the planet positions and make symbolon card tables according to the calculated constellation. It can draw the classical circular horoscope also.

Yet another astrology software. Focused on Primary Directions. Based on Swiss Ephemeris. Still has a lot of things in queue to implement.

Telescope mirror surface error analysis from interferograms. Includes 3D solid model, color Contour plot, quality metrics, and surface profile.

A web atlas using the planetary body renderer, Xplanet. Explore the solar system. Overlay clouds, cities, weather forecasts, and more. Navigate by point and click. Search global databases.

Displays the phase of the moon in the system tray. Additionally, a window can be displayed that shows user configurable data about the moon (rise/set times, percent illumination, etc).

Arduino al/az mount controller based on lx200 protocol.

I can not find a simple graphical rutin to draw a geographic sphere with geo-coordinate grid on the Canvas. I need to move , rotete this globe and change the eye point. And an other function to get a geographic coordinates from mouse position.

C++ code for a N-Body Simulation. Computational Physics with graphics.

The Universe Simulator project's goal is to provide a set of libraries for simulating all known and understood physical phenomena.

retep is a collection of Java API's covering PDF, XML, J2EE , Swing and now NetBeans modules for displaying astronomical maps, controlling modern "Go-To" telescopes - all in java., and accessing online databases.

A C library containing working theories of motion of solar system objects that have been published in the Astronomical Papers prepared for the use of the American Ephemeris. Currently this includes Newcomb's theories "Tables of the Sun", "Tables of Mercury", "Tables of Venus", "Tables of Mars", "Tables of Uranus", and "Tables of Neptune", Hill's theories "Tables of Jupiter" and "Tables of Saturn", as well as the theory known as "The Improved Lunar Ephemeris". Various other theories from selected astronomical journals are also included.

Gravitation is an interactive program, which tries to simulate the dynamics of celestial objects in their mutual gravitational field.

cmdline (used by Image16) and ui interfaces to ANSVR astrophotography plate solving images (FITS, TIFF, PNG, JPG, PXM, RAW and XCF) are submitted to ANSVR astrometry engine producing a text file with the plate solving result and a .png plot file TIFF, PXM, RAW and XCF files are converted to FITS by the cmdline utility all files are loaded and converted to FITS by the ui utility

This application is used as bridge from ASCOM libraries to an external app using a TCP socket. You can find more information about this app using the Wiki project.

AIRE (Astrophysical Integrated Research Environment) is a set of computing facilities initiated by Tsinghua Center for Astrophysics , which aims to aid astrophysicists collect, store and analyze data.

The goal is an Ascom driver for parallel port connected, telescope controlling stepper motors.

Telescope drive using a ATMega2650 and RAMPS 1.4 Board. The interface uses standard LX200 instructions. Different timers are used for RA and Dec Axis to achieve higher and more precise stepper frequencies.

CometCube - software that used to analyze datacube(FIT format) obtained from radio telescope. This project is using IDL evironment and language.

Application for logging, planning, and searching astronomy observations. Written in Python/Tkinter with support for xmlrpc/SOAP as a secondary goal.

Some astronomy calculations testing

Astrophotography Lab (APLab) is a free program intended for anyone interested in astrophotography. It has two main purposes: - Interpreting data extracted from your astrophotos to produce useful information. - Using this information as a help for further improving your imaging results. The program consists of four main tools: an analyser tool, a calculator tool, a simulator tool and a plotting tool. The tools are connected, allowing you to transfer information between them, and easily go all the way from measuring your camera's sensor to finding the optimal settings for your next imaging session. APLab supports a wide range of CCD and DSLR cameras and telescopes by default, and you can easily add the necessary information for your own equipment.
