Description

The OIII layer was extremely noisy due to faintness of the emission, which was impossible to remove. As a photographer noise doesn't bother me, on the contrary, I like the texture. But for astronomy it's more usual to remove all noise. So I park this here to wait for clear skies or next year to add signal to the OIII layer.
