What is Astro Live Stacker?

Astro Live Stacker (ALS) is an open-source application dedicated to live astrophotography.

Its primary role is to enable real-time processing of astronomical images, a technique called livestacking.

This approach involves aligning and stacking successive images as they are acquired to enhance their quality by revealing more details and reducing noise.

ALS supports various image formats, runs on multiple platforms (Linux, Raspberry Pi, Windows, Mac), and offers features like live session sharing via an integrated web server.

The Team

Gilles Le MARECHAL: The initiator of ALS, a man of limitless thinking. Our muse...
Sébastien DURAND: Tireless tinkerer, Python tamer
Thibault NOTARGIACOMO: Math whiz and image processing expert
Fred CORNU: Oils the gears, stabilizes, automates
Stéphane HUBERT: Spends his nights testing ALS and coming up with ideas like the integrated web server

History

ALS was born from an initial attempt at livestacking using Ekos to control Siril via custom shell scripts. These shell scripts then evolved into Python code. What started as a small toy for a few friends spending their nights photographing the universe has grown into a full-fledged application used worldwide.

Mission

Ensure ALS is available on all platforms
Offer intuitive and user-friendly tools
Be dedicated to the principles of open source and sharing

Our goal is to provide a simple, unobtrusive, and high-performing software. ALS is designed to be intuitive, allowing users to focus on what matters most: capturing the wonders of the night sky. We strive to maintain a balance between ease of use and performance, offering advanced features without compromising the user experience.

With ALS, we aim to make astrophotography more accessible and enjoyable for everyone, meeting the needs of enthusiasts at all levels.
