I don't what you have presented is an obvious artefact, it is real. the image view is different from the eye piece view for many reasons.
The colour is the most obvious. My Lunt shows a red image, this is not real either just a result of the filtration. I then image in monochrome, then change it to orange purely for aesthetic reasons, the Sun has been depicted as orange for centuries in art.
Stacking and processing I think is just a way of beating the conditions.
Yes we are amateur "scientists" and yes, just occasionally I certainly do have delusions of grandeur 😀😀😀
Seriously though, many contributions to science have been made by people to ourselves.
