Apologise if this somehow is a Gigantic Post--not clear to me how to respond to an individual post.
It was dispiriting to follow up the link given by Astro Mark (in the discussion of this APOD) to a previous APOD which I had much enjoyed and which is asserted to be a montage which, in my perspective of what an APOD is, would be a fake if not explicitly explained what had been done.
As far as this APOD, out of curiosity I ran it through a site which estimates the probability that an image is human-vs-AI generated. The site gave this one a probability of 85% for being a human photograph--the converse 15% probability of being AI generated (which Astro Mark did NOT suggest) would, I think, be consistent with digital manipulation of the sort suggested.

As much as we do not question the educational value of studying solar activity, this image leaves me very puzzled. I believe that it is not a correct representation of reality even if made according to an HDR technique.
For one thing, the Sun is not aligned with the brightest part of the reflection on the sea, which seems to have been taken when the Sun was higher and further to the left.
Also, it is possible to see how the image is a photomontage by looking at the lower right branch at the point where it touches the horizon. A step on the sea horizon is visible at that position.
Another doubt arises from the fact that the sea horizon disappears to the right among the bushes and is no longer visible.
I checked the forum for other work by this author and found that he is responsible for a fake APOD image for which he has been much criticized by the astrophotography community. You can read the discussion on this same forum at the following address:
