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.

Aiming and controlling equipment:
Align assistant with the polar scope (Takahashi or EQ6)
Align assistant with the King method
Focusing assistant
Pipeline for the aiming model
GOTO function using integrated catalogs (planets, asteroids, Messier objects, reference stars, NGC, IC, Moon)
GOTO function using another charting planetarium tool (Guide, Carte du ciel , Skychart)
Remote control from a computer
Check position and time via GPS (through a serial or Ethernaude link)
Control of filter wheels
Virtual control pad
Autoguiding
Supported telescopes : LX200 protocol (with special features of Audecom, Skysensor, losmandy, It-lente, Mbartels), Ouranos, Temma, Ascom, Celestron
