That’s the first photo showing the “unfocused” star. The title implies that the Webb scope has finally fine-tuned its lenses so only one image remains.

This then is very old news.

“Very old” as in Sunday, like the article says. That’s when this picture was taken.

Re: "The title implies that the Webb scope has finally fine-tuned its lenses so only one image remains."

You forgot to read the article.

Once all 18 mirrors are aligned, the telescope has to adjust its position almost every second to keep its focus within a range of 10 nanometers. It does that by tracking the known distance between multiple guide stars, second by second.

The entire universe is in constant motion, which means the whole telescope must make minute adjustments second by second.
