Other projects I developed, most of them based on JPARSEC.

[LEGACY] Telescope control system

I'm developing a control system for an amateur observatory, including the control of telescopes and cameras, but it seems I'm not going to finish this project in some years. The idea was to use this software for a telescope we have at OAN for outreach, but software requires a lot of time to develop and maintain and for several reasons I was not convinced that the idea deserved such effort. Most of the features are implemented, at least in a basic way, but camera control and image reduction, among other things, are not finished. Project files are available here, but dependencies are not included. Below there is a youtube video showing the program in action. It's a pity, it was looking good. In case you continue or fork the project please let me know.


I may finish this project some day for my own observatory.

Solar System in 3d

A summer project I developed to more or less mimic the Celestia space simulator in Java. Not finished, but fully usable. Project files are available here, and a standalone runnable version for Linux and Windows is here. More information in the blog entry page.


Mars/Moon in 3d

Another project to simulate the surface of Mars and the Moon in 3d. Please go to the blog entry page for description, control keys, and project files. A standalone runnable version for Linux is here. With some work similar to that done in the previous project (Solar System in 3d) you may run it also on Windows.


ClearSky for Android

I have created a planetarium for Android. Well, another way to say it is that I have worked very hard for five years to develope one of the best planetariums for this platform. Some steps were documented in the blog, almost most of them not, and, in fact, I have the blog quite abandoned, partialy because I've been absorbed by it. The details about the program and the installation web page is located at the Android Play Store.


JPARSEC is very powerful on sky charting, and as a desmostration I created an sky atlas with a layout identical to the well known Sky Atlas 2000, by Wil Tirion, but with slightly less objects to be more friendly for beginners and also to allow to be printed in a more confortable A4 size. Main difference is that the atlas was created for equinox 2013, showing the trajectories of the external planets, the Sun, 2012 DA14, and comet ISON. It requires an update yearly, but I think it is more useful. Another difference is the deep sky textures (and Milky Way!) shown in the dark edition, and the radiants of the meteor showers. It is my first approach on a sky atlas, and obviously some details can still be improved, but the result is great. A description of the atlas is provided in my old and my new blog posts.

The normal edition of the atlas for 2013 can be downloaded in PDF format here, and the dark edition here. Possible updates will be posted here.

Here are the charts for recent years. Starting from 2019 the quality has improved a lot, with seasonal sky charts and a calendar of astronomical events (available only from 2019).

2021: normal edition, Spanish version for Spain peninsula, Spanish version for Canary Islands.

2020: normal edition, Spanish version for Spain peninsula, Spanish version for Canary Islands.

2019: normal edition, Spanish version.

2017: normal edition, dark edition.

2016: normal edition, dark edition.

Bungee Star Atlas

Angelo Nicolini is the author of the Bungee Star Atlas, a detailed atlas based on JPARSEC and available in English and Italian with different levels of detail. It is in development, but already available, and far superior to my own atlas. Project code is available at bitbucket.

Web ephemerides server

A web ephemerides server that produces accurate astronomical ephemerides of solar system bodies is now available. To have a good performance, the accuracy is intenctionally slightly below that of the JPL Horizons for dates far from year 2000 (in current dates accuracy is similar), but the quality of the charts and the interactivity and performance when simulating astronomical events if by far above any other web tool. In addition, probably you have never seen such a level of completeness and detailed data. Current version is available in Spanish and English.

Here are some interesting phenomena you can simulate interactively with this ephemerides server using the applet described below. You need a web browser compatible with Java applets, like Waterfox or Pale Moon:

New sky and Solar System simulator applet

A multiplatform (maybe biggest ever?) applet that simulates the sky and the planets as seen from a given place and with a given telescope and ocular. Java 1.6 is required to launch this program, and Spanish and English versions are included. Download it here and enjoy it! Applets can only be executed in the web browser using old programs (you can try Waterfox or Pale Moon browsers, or use Rekonq in Linux), but a standalone executable jar file like this one can be downloaded and executed directly with Java from your desktop (double click on the file or open it with Java Runtime, or the command java -jar planetario.jar).

With an adequate browser you can also try it online in English or in Spanish. In the first online execution the applet requires to download more than 30 MB of data.

=)This is extraordinary. I have not seen anything even close to this as a Java routine anywhere else. Thank you very much for providing the applet. We will explore it and then have students give it a test drive too”, John Kielkopf, Professor of Physics and Astronomy, University of Louisville, USA.

The applet was updated for the last time on July 31, 2020.

Practices on Observational Astronomy

Windows program to learn astronomy. It was made as my final degree project with Windows 95 graphic libraries (a long time ago!) and using Fortran 90. It was so nice that I decided to never use Fortran or those graphic libraries again anymore. The monster can still be executed in XP, but be sure to maximize the window and put it at the top left corner. Download it here (or here for the Spanish version) and enjoy!

Solar System Simulator

Several applets that shows the Solar System, the sky, and artificial satellites. Also quite old. They can be downloaded here.

  • Solar System Simulator: here. Small version between years 1900 and 2100 AC.

  • Solar System Simulator: big Spanish version between 1000 B.C. and 3000 A.C. here.

  • Artificial satellites: here. In Internet Explorer say yes to the question that pops up to automatically download updated orbital elements, in other browsers say no.

  • Sky: here.

Virtual Visit

An applet to explore certain places based on photographs taken from every possible direction. Quite old, but funny. There are two virtual visits available:

  • IRAM 30m telescope: visit the 30m radiotelescope at Loma Dilar (close to Veleta peak at Granada, south of Spain). Download it from here, or see it online here.

  • Barco de Ávila: visit the little village where I spend my holidays, located at the central-west part of Spain. Download it from here, or see it online here.
