Audela - Latest News

Info about latest versions

A few articles in French of our Wiki (see item "Version de développement") detail new features in the latest versions of Audela.

Audela - What is it?

Audela is a free and open source astronomy software intended for digital observations (CCD cameras, Webcams, etc.). Its concept is entirely new, because whilst it features advanced image processing and acquisition functions like existing software, its originality lies in the fact that it is entirely reprogrammable using simple scripts. It has been written for both Windows and Linux platforms and can control many telescope mounts and cameras or DSLRs.

Read the former French documentation

This is the former documentation and it is therefore not up to date. Please note that it is also in French but maybe it can help you code TCL scripts and we make it available as is. The Documentation link in the menu at the top of the page refers to the new documentation which unfortunately still lacks information.

What is Audela different?

• Audela is fully customizable. You can even customize its main interface.
• Audela enables not only camera control, but also full telescope control, locally or at long distance via a network.
• Audela has been especially conceived to meet the needs of the amateur astronomer, from beginner to advanced observer.
• Available in 6 languages: French, English, Spanish, Italian, German and Danish.

Who are we?

Audela likes "cassoulet" which is a well-known course based on beans and meat typical of Southern France. Visit the Pixels & Cassoulet website of the "famous" network of amateur astronomers from Toulouse (city in Southern France).

The Audela Core Team consists of a few amateur astronomers in charge of coordinating and coaching Audela development:

• Alain Klotz: development, coordination
• Denis Marchais: development, coordination
• Michel Pujol: development, coordination
• Robert Delmas: development, coordination of the translation process
• Christian Jasinski: communication, translation
• And all the people contributing to Audela development.
