They're sourcing the images from private imagery sources like Planet and Maxar. Images from publically funded satellites like Landsat and Copernicus are already freely available for download. It would be nice if Planet and Maxar made it easier for people to buy their images directly but this seems like an okay solution for now.

Feel free to zoom in, it's a large image.

Took photos of the moon whenever I could for the past month or so, and finally compiled them into this phase panorama!

Each photo took about an hour to finish, and are stacks of somewhere around 100 images (varies by image) from videos of somewhere between 1k and 3k frames (also varies by image), taken on my Nikon Z5 camera and F/4.5-5.6 70-300mm lens.

Stacked in Lynkeos, post-processing done in either Lightroom, Darktable or Photopea (again varies by image).

Final panorama compiled together in Photopea.

The central full moon image is from the moon/mars conjunction on 12/8/22

Enjoy!

Don Mitchell's web page has perhaps the highest quality images taken by the Venera probes. He gained access to the raw data from the probes and used his expertise with modern image processing tools to extract much better quality images.

This and this are great examples of his work. Quite something to see these, taken at the bottom of a ~460 °C, ~90 bar supercritical CO₂ ocean.

Edit: Oops, just saw /u/UmbralRaptor's comment, already referencing Mitchell's page. But I'll leave this one as I think it adds detail.
