Simple frame grabber application (similar to xawtv) that can capture directly into a series of FITS files, suitable for further processing with IRIS.

Lxnstack is a program designed to align and stack astronomical images (both planetary and deep-sky). The features of latest version are: * Several stacking methods (average, median, sigma-clipping, ...) * Two automatic align method: align-points; phase correlation, * One manual align method. * sub-pixel precision (0.1 pixel for phase correlation and 0.01 pixel for manual alignment). * Automatic image derotation. * FITS file support (by installing the python2 package 'astropy') * Hot pixels suppression algorithm * CR2 files native support * Can load/save video * Grayscale RAW image support * Editing of result image's levels. * Light curve generation

TODO

A short and simple hydrodynamic Godunov code using a cell-based structure. This program is free to use. It was designed mainly for teaching purposes and it is made freely available in the hope that someone may find it useful.

This is a Delphi/Pascal class that implements a realistic simulator of planetary systems. You can design your own solar system, create custom planets or other objects and establish their gravitational relations using groups. See demos for Windows using OpenGL.

Project moved to Google Code since SourceForce is a broken, buggy, non-responsive service. I had to re-log in over 100 times just to change this description. Please visit the project at http://code.google.com/p/starflighttlc/ for the latest version of th

openSkyMatch is a collection of Linux shell and Python scripts designed for the OpenScience Observatories program. It automates the identification and matching of detected celestial objects in locally captured FITS images with entries in large-scale sky catalogs, notably Pan-STARRS1 DR2 (II/389/ps1_dr2). The toolkit supports data preprocessing, coordinate correlation, and catalog-based validation of astronomical detections. All tools are open-source and optimized for reproducibility and transparency in citizen science astronomy.

Programa para simular un ocular reticulado mediante una webcam. Permite utilizar una cámara web compatible con v4l2 para hacer alineación polar de una montura ecuatorial con el método de deriva (drift method)

A php port of the solunar tables calculator. Calculates Solunar Tables for any position on earth. Solunar tables are used to predict the best days and times of day to go hunting and fishing.

This driver is derived from the PWC driver found in the Linux kernel. It adds V4L2 controls (`V4L2_CID_FLASH_STROBE/STROBE_STOP`) to drive the led present on some cameras. It also synchronously sets the video mode when power_save is off. This driver may be used to control long exposure modded webcams (SPC900, TouCam,..) when the led is used to trigger long exposure (this avoids the use of an additional serial port).

pyastrolib is a python library providing professional astronomers a robust set of tools for astronomical data analysis. This project will provide all the functionality as NASA's IDL Astronomy User's Library in addition to other planned features.

Open source development of a tool for the astronomy community to interact with the GRB Coordinates Network (GCN) broadcast of real-time gamma-ray burst (GRB) and X-ray Flash (XRF) information. Support for satellite packets: HETE-2, Integral, Swift

This project offers a python binding to the libindi library. It uses the Simplified Wrapper and Interface Generator (SWIG). You may generate a PyIndi module which mainly defines an IndiClient class. This class could be used to build python scripts able to interact with indi servers using sendNew* methods and implementing new* methods of the BaseMediator class. PyQt applications may also be built on top of IndiClient, thus allowing rapid development of GUI Indi clients. Besides Python there are also bindings for node.js, Tcl (incomplete) and PHP (not useful). As application examples you will find a Python Websocket server with which you may build a web application interacting with Indi servers, and a simple PyQt application similar to the Kstars Indi Control Panel (was built as an exercise). Finally there is an equatorial mount 3D simulator written with Freecad and Python, planned to be connected with the PyIndi module. *** The pyindi-client binding has moved to github. ***

qapod - Fetch each day a new picture from web, store them and put them onto your background, now mainly apod (astronomic picture of the day, http://antwrp.gsfc.nasa.gov/apod/astropix.html). It can also greet YOU with a nice picture every morning :-)

This program should compute ZHR from data contained in IMO VMDB (http://www.imo.net/data/visual), or other sources with same structure. ZHR should be calculated on arbitrary interval. It should produce analytical and graphical output.

a program to retrieve magnetic power spectra from Faraday rotation maps using a method described in http://arxiv.org/abs/0912.3930

seti-stat is a simple bash script that will retrieve your SETI@home statistics using HTTP protocol, egrep and lynx browser.

RochePlot is a Fortran code using PGPlot to plot a series of binaries to illustrate the key stages in the evolution of a binary star

Java science library. Project contains modules for physics units, particle and quantum physics, molecule, chemistry and universe definitions, also additional math classes.

ruby-sphere is a set of libraries and user interfaces written in Ruby to calculate apparent positions of stars with a moderate accuracy. Its goal is to provide an easy way to plan astronomical observations.

Package of programs allows to make astrometric reduction of xy-coordinates tables, obtained by mesurements of any stellar frames.

rx2fits is an SDR code for the rx888mk2 direct-sampling receiver that streams spectral data with frequency up to 65 MHz to FITS files. This code is for the direct-sampling input of the receiver, which transmits real samples over USB3 at up to 130 MHz sample rate. rx2fits processes these samples to spectral intensities via a Fourier-transform poly-phase filter bank, which provides spectral resolution approaching the spectral bin width with good stop-band and adjacent-channel rejection. Sample rate, Fourier bin count, PFB frame count, integration time and receiver gain parameters can be set. Utilities for device enumeration, firmware upload, display of FITS header, file viewing, and for measuring sample rate and sample statistics are provided. The device interface is Ruslan Migirow's librx888 and dropped samples at 130 MHz are negligible. Runs on linux computers under .Net.

This program will enable you to find every solar eclipse in between about 2500 BC to 3500 AD. The central line can be displayed graphically and saved as a JPEG or PNG image file or as a PDF document.

sastrocam (simple astronomy camera) -- simple camera control for astronomical imaging in Linux. Provides a simple web interface to the camera that will function well for remote control over a low bandwidth link.
