If you’ve got an Nvidia card in your system then this look ‘potentially’ fantastic ….. and it’s free!

Now I’m in the office and trying this it seems it doesn’t work now (Oct2022). It did at some point but the comments on the video and my testing in Firefox, Chrome and Edge seem to point at it being shut down. That’s sad as it could have been great for creating skymaps for us.
That’s a shame - I hope they make it available again. I’ve used NVIDIA canvas before which goes in that direction and I really liked that it was available locally and offline. Hopefully they’ll also release a similar installer for the panorama creator soon.
