I was not entirely sure how I wanted to blend the SII data to the existing bicolor image. I think a 50/50 mixture of OIII/SII for the green channel looked the best.
Luminance was a blend of Ha/SII/OIII in equal proportions.

If this user has been harassing you, and you shadow-ban them, all their activities on your content will be invisible to everyone except themselves.
They will not know that they have been shadow-banned, and the goal is that eventually they will get bored while having caused no harm, since nobody saw what they posted.
You will remove your shadow-ban on this user, and their comments, messages, etc, will appear again on your content.

The image will be permanently deleted and cannot be recovered. All its revisions will be deleted too. Are you sure?
You will delete all other revisions (if any), and the originally uploaded image, leaving the current revision as the final and only version of this image.
