Description

I did some test shots for my .75x Esprit 100 setup of this region as preparation for another project.
At F/4 the Hα signal was pretty strong, so I decided to get some more O3. This turned out to be quite a challenge, as the O3 is very faint in this area.
While processing and creating a sum-luminance from Hα and O3 the different brightnesses of the filaments came apparent. This results in a quite specky O3 presence in those filaments in the full color image.
