Images of the Sun in 700-800 nm wavelength, deep red part of spectrum. This telescope resolves down to 0."045 or so arcsecond size so at 1 AU distance, about 30 km in diameter features on the surface of the Sun.

A Swedish Solar Telescope in the Canary Islands has been producing pictures like this for almost twenty years.

Yep. Tossed this together for comparisons...

. Also... this existed 6 months prior to the Inouye:

Additionally, https://astrobites.org/2012/07/04/a-hot-test-of-gr/ contains granulation images from 2012. Inouye may be high res... but the image provided in the article definitely isn't far from the pixel count of the others. Is there a full size image around?

I guess nothing new under the sun.

Have you informed NASA? This news is ground breaking. I am sure they would be interested to see your findings.

NSF's newest solar telescope produces first images, most detailed images of the sun

What I reported is in the phys.org report concerning the small size of features observed on the Sun.

FYI, this morning I enjoyed views of sunspot 2757 using my white light solar filter and 90-mm refractor telescope. This sunspot is moving slowly across the Sun as it rotates, reported at spaceweather.com on 25-Jan-20. A bit larger than earth size as some images show. Distinct plage visible all around the darker core. However, my telescope does not see features on the Sun about 30-km in size as phys.org reports on this new, solar telescope

"Earth's most important star" might be one of the most nonsensical things I've ever read.

With 2 alternative sources of such "never before seen imaging," would have been prudent/smarter to have pursued another investigatory project in the solar arena that would enhanced solar knowledge.

Great that it is upgradeable with various variations but that seems eventually obsolete with advancement. Cross sectional penetrating observation would be oso grand and this sounds like a goal. That moves closer to understanding mass existence which looks like an aberration of equilibrium in a non existent media but generally linear, self structuring, and originating from infinitely multiple sources. Seems there would need to be some "external" excitability to create the pressure aberrations.

Here is another report on this new solar telescope, Newest solar telescope produces first images, "The Daniel K. Inouye Solar Telescope has produced the highest resolution image of the sun's surface ever taken. In this picture, taken at 789 nanometers (nm), we can see features as small as 30km (18 miles) in size for the first time ever. The image shows a pattern of turbulent, 'boiling' gas that covers the entire sun. The cell-like structures -- each about the size of Texas -- are the signature of violent motions that transport heat from the inside of the sun to its surface."

The cells in the image are about the size of Texas, about 660 miles wide or near 1060 km. The Sun at 1 AU distance, those cells are about 1.5" angular size and the image shows details even much smaller, down to 30 km size. That is something here in solar observations.

Astronomy in Hawaii has been fraught with protests, but there is growing support among Hawaii residents, especially the Kanaka Maoli community. But if Gov. Ige and Mayor Kim don't understand it's their job to uphold the law this could well be the end. Tourism and the military are not the best sources of revenue for obvious reasons.
