For anyone that wants to buy the 139 megapixel image for printing, it's $50 here: https://cosmicbackground.io/products/fusion-of-helios
I'm not affiliated, but I've been seriously debating it for a long time. The photo is a composite of the sun and the sun's heliosphere from the 2017 eclipse. One of my favorite images of the Sun.
Do you think that is original or some AI enhanced copy of the twitter img?
It’s the original. Andrew McCarthy links to it from both his Twitter and Instagram accounts. It’s his own website.
Perhaps rr808 is referring to AI upscaling. As in, are these 139 proper megapixels or upreased to that size?
It's made from over 90,000 individual images that have been stitched/combined together. I'm not the original photographer so I can't comment on his process, but I think it would be silly to use upscaling (AI or otherwise) when your starting data set likely contains multiple gigapixels.
