- Cameras: SKYnyx2.0M (since 2007), ToUcamII Pro RAW B&W (until 2006)
- Animations are made from pictures captured once per minute or 2 minutes, played at 10 images/seconds.
- Each picture is built from a 1 minute long video of about 3600/4000 frames captured at 68frame/s, stacked into 1 picture after selection/alignment with AS2!
- All pictures are taken through B&W cameras, colorised artificially to mimic the H_alpha filter colour.
