There are many astronomy software programs dedicated to hobbyists, students, and educators. Most of them give you the possibility to visualize astronomy objects. But few are equipped with advanced features reserved for professional environments. Those features should permit you to conduct scientific research, analyze data, and handle operations involved with telescope maintenance. In this article, we picked what we think are the 5 best professional astronomy software solutions. All of them are fitted with telescope control support, too.

What professional astronomy software tools should I get?


C2A main window

C2A (Computer Aided Astronomy) is a free planetarium software solution for Windows computers, which can be used in professional astronomy. Featuring an intuitive graphical interface, it gives you the possibility to create detailed views of stars.

It has a database of stars from the Smithsonian Astrophysical Observatory (SAO), Washington Double Star (WDS), Gliese Catalogue of Nearby Stars, Hipparcos, and other sources. You can create your own catalogs, too.

Besides zooming in and out, you can get information on any selected star, adjust visibility settings, create an observation planner, and put together a scheduler. Telescope control is supported as well.

C2A provides you with multiple tools. For instance, you can set solar system trajectories, filter asteroids and comets, view sunrise and sunset times, check out the moon phases, investigate planet positions, or set field markers.

As far as images are concerned, it’s possible to make adjustments, perform analysis, use a digitized sky survey, browse an atlas of object pictures, and change background images.


  • Free
  • Intuitive graphical interface
  • Lets you calculate the trajectories of celestial objects


  • The interface may seem cluttered for some

KStars main window

KStars is a free and open-source astronomy software tool that can be used by professionals to observe the night sky from Earth’s perspective. It’s also possible to switch to day mode by controlling time settings.

Delivered in an easy-to-use graphical interface, KStars simulates a space environment for investigating 8 planets, up to 100 million stars, approximately 13,000 deep-sky objects, asteroids, the sun and moon, comets, satellites, and supernovae.

Thanks to adjustable time settings, you can carefully observe elaborate celestial events which took a long time to unfold. You can set coordinates manually, quickly locate objects with a search function, and enable tracking mode.

Additional tools are available to help you convert coordinates, calculate time, plan solar system conjunctions, or predict eclipses. You can check out a sky calendar, generate graphs for objects by altitude and time, and run a solar system simulator with XPlanet, if you choose to install this free third-party tool.

Depending on what compatible equipment you have and wish to use, it’s possible to integrate a telescope, eyepiece, lens, or filter with the telescope control software.


  • Free and open-sourced
  • Simulates 8 planets, up to 100 million stars, approximately 13,000 deep-sky objects


  • May cause issue son old PC systems

Stellarium main window

Stellarium is a top choice among many professionals when it comes to astronomy software. Just like the previous listings, it’s free and open-source, facilitating a 3D simulator for planets, stars, and other celestial objects.

You can explore numerous stars, deep-sky objects, constellations, nebulae, novae, supernovae, the Milky Way, meteor showers, and others using a powerful zoom. These are accompanied by photo-realistic images and various effects, like star twinkling.

Plugins are supported, which means that you can add extra functionality to Stellarium. For example, you can connect your telescope and configure settings, simulate ocular mode, or load new solar system objects, artificial satellites, and constellation pictures.

There are many professional approaches to this astronomy software solution. For instance, you can install the VirGo extension to view and analyze data from the archive of ESO.


  • Free and open-sourced
  • Supports plugins

Expert tip:


Some PC issues are hard to tackle, especially when it comes to corrupted repositories or missing Windows files. If you are having troubles fixing an error, your system may be partially broken.
We recommend installing Restoro, a tool that will scan your machine and identify what the fault is.

Cartes du Ciel (Sky Charts)

Cartes du Ciel

Cartes du Ciel is a free and open-source astronomy software tool that boasts a wide range of options and configuration settings for professionals.

It renders a sky map that allows you to investigate more than 9,000 stars and 10,600 deep-sky objects, including planets, comets, asteroids, nebulae, constellations, and solar systems.

The catalog can be enriched by downloading additional resources. And you can use an advanced search tool to quickly track down objects. The orbital motion of solar system objects can be plotted after configuring simulation settings.

It’s possible to save images and record animations to file, change the coordinates and chart mode, select the types of objects to display by applying catalog filters, toggle night vision, set a different field of vision, as well as increase or decrease the number of stars and deep-sky objects.

Telescopes are supported by Cartes du Ciel, which can be connected to your device using INDI, ASCOM or manual mount drivers. Aside from customizing telescope preferences, you can synchronize data and activate slewing or tracking mode.


  • Holds detailed information about each known celestial object
  • Supports telescopes
  • Can be used to plot the orbital motion of celestial objects


  • Celestial objects only have text associated with them, no pictures
