> The telescope achieved superior resolving power and produced clear images of the surface of the Moon.

1. Superior to what? Certainly not convetnional lenses.

2. Why are these images not published?

To self-answer the 2nd quesion, the image is published in the linked article, and accessible free-of-charge in the pre-print published on arXiv (figure 5d): https://arxiv.org/pdf/2205.12739.pdf

"We identified some features of the lunar surface, such as the Sea of Rains, the Sea of Serenity, the Sea of Tranquility, the Ocean of Storms, the Sea of Tranquility, and the Copernicus crater, from the obtained image"

Some of these are visible to the naked eye. I'd like a better explanation of how exactly the images are 'superior'

The article had a discussion about how existing metalenses were limited in size. So, I assume they're saying this metalense is superior to the state of the art in the field of metalenses.
