Description

HDR composition of:
- 20 images at 1/4"
- 20 images at 30"
- 9 images at 300"
Very hard to make the 4 central stars visible without having a bad looking oversaturated but flat picture... (yes, very strange). This is the kind of picture on wich the imaging was very easy, but processing took a long time with a lot of "ok, the details are here, but it's awful to the eyes, let's redo everything from scratch!"
