A planetarium software that shows a 3D simulation of the night sky
Stellarium renders 3D photo-realistic skies in real time with OpenGL. It displays stars, constellations, planets, nebulae and others things like ground, landscape, atmosphere, etc.
SkyChart is a software to draw chart of the night sky for the amateur astronomer from a bunch of stars and nebulae catalogs. See main web page for full download. This software is part of a full suite for astronomical observation: https://sourceforge.net/projects/ccdciel/ https://sourceforge.net/projects/indistarter/ https://sourceforge.net/projects/eqmodgui/ Requirement: https://sourceforge.net/projects/libpasastro/ See also: https://sourceforge.net/projects/indi/
Real time satellite tracking and orbit prediction
Gpredict is a real-time satellite tracking and orbit prediction application. Gpredict can track an unlimited number of satellites and display the data in tables and various graphical view.
AudeLA is a TCL extension aimed at providing amateur astronomers with image processing, telescope controling, ccd camera driving, and various astronomical algorithms.
Echoes it's a radio spectral analysis software for RTL-SDR devices,
Echoes it's a radio spectral analysis software for RTL-SDR devices, designed for meteor scattering purposes. RTL-SDR are very cheap Software Defined Radios that uses DVB-T TV tuner dongles based on Realtek's RTL2832U chipset. 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, GNUplot) 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.
Jewish prayer times
Android application that displays list of halachic/halakhic times for Jewish prayers (zmanim and zmanei tefillot).
HSPI does parallel capture and sky surveys.
HSPI offers to the astronomer the possibility to capture pictures from the CCD camera in a fast and intuitive way, keeping under control all the instrumentation in posses. HSPI can control the CCD camera, the mount, the focuser, the filter wheel and the dome from a single interface, and not only this: these features can be added on as many observatories and instrumentations you want. HSPI is ASCOM and INDI compatible, so if you want to use particular setups like Linux computers connected with your instrumentation and control them from remote then HSPI is your choice! After a few clicks you can see the images coming from your cameras connected through Internet or your LAN. HSPI saves your pictures in various formats: Bitmap, FIT, JPEG, PNG, TIFF are the picture formats supported.
