My antiblooming seems to be set correctly now : compare the stars size and shape with the above pictures.
I used a diffraction focuser system to help focusing.
Seing that the blue part of the nebula is really pale, the same picture has been processed with paint shop pro as final step : colors, adjust, hue map, and only saturation shift at +16%.
