Post-process "cloning"?

Greetings from BobV! New poster -- but longtime APOD fan -- here. (The APOD Archive URL "lives" in my favorite bookmarks bar...)

I agree that this full Carina photo is one of the most spectacular and beautiful HST images -- ever! However, this one has a couple of places that make me wonder if the post-processing includes "image repair" using something like the Photoshop "clone" or "rubber-stamp" tool.
<P>
In the full image, about 25% up from the bottom, and barely to the left of the centerline, there is a "stack" of parallelogram-shaped regions that look much like the results of "cloning" to me:

...possibly to "fix" a data-dropout or non-imaged section.
<P>
There appears to be at least one other example in this image. Is this my imagination?
<P>
I would not expect image data modification in HST data released for scientific purposes. OTOH, does anyone know if the HST Team might "repair" a gap in the data -- for public display images only?

Peculiar how there are two identical shapes .. the dogoctopuses.

A new species has been born?
If man were made to fly he wouldn't need alcohol .. lots and lots and lots of alcohol to get through the furors while maintaining the fervors.
