This is fantastic.

I immediately wondered how he managed to seamlessly mosaic together what is surely hundreds of images and thousands of subs. Here are the details: https://space4everybody.com/processing-details/

And equipment: https://space4everybody.com/technical-details-equipment/

Nothing too fancy (in astrophotography relative terms). A decent refractor and mono camera (such parameters have come down in price by 2-3 times, ASI2600MM is comparable) and most importantly, a solid pier/mount.

  267 Individual panels (including reshoots)
  12,816 Individual light frames
  65,000 x 35,000 in it’s entirety
  5 States traversed to image
  640.8 Imaging hours
  500+ Editing hours
  2.5 Gigapixel Image
  1.6 Pixel scale
  5 Years
  1 Mosaic

Just WOW

Unfortunately they don't seem to have a link to the final "full-res" image. I'd love to put that with my collection of other massive-res images. My screensaver pans between random spots on massive images in a folder.

They sell their photography. I'm sure you can reach out for a price quote.

Hey, would you share your library publicly or privately? I've been looking for something like this :)

Also, check out dezoomify[0]

My libraries are always made of images I've found online. I've lost two libraries over time so I'm on my third one now.

I haven't added to my library in a while, but I might spend a few hours looking for some more images this weekend.

The current stats for my library:

At the moment it's 1.47gb for 75 images. I'm not sure where I have copied each image from, but I know some are either from ESO or NASA's image of the day, except that I find the original non-browser friendly images and download those. If I can get an image I like larger than my 5k screen, I'll add it to my library.

My average image size is 7156x5412.

My largest image is 324,000,000 pixels (18,000x18,000), pretty sure it's the Orion Nebula.

My smallest image is 2,958,400 pixels (so only 1720x1720), however any image that is surrounded by black (like a planet with no stars around may be cropped from time to time). Since my screensaver puts black around any images smaller than my 5k screen, it still works out. I'm pretty sure the smallest image is an image of Uranus from the Voyager that flew past it and I wanted to make sure I had an image of at least every planet in the Solar system and that was the best image of it I could find.
