Is it just me or are 4k monitors running in 1080p worse than straight 1080p monitors?
Yes, since neither GPU drivers nor most displays currently support integer scaling. See http://tanalin.com/en/articles/lossless-scaling/ for more a more in-depth explanation.
I took 50k images of the night sky to make an 81 Megapixel image of the moon

I mean would the display need to know - just GPU drivers should be able to send a 4k signal that has 4px squares each of one colour? Interesting though.

#33~~I obviously don't know enough about images... Why would you store this as a jpg and not a LOSELESS format?~~ The full resolution image is in the comments, it's uploaded small because of Reddit https://drive.google.com/file/d/1lGDV6jOHc0v5UdkxcqYShqhKBz_...
Edit: misstated Leo instead of lunar, Leo is low earth orbit

#34Great! It is interesting, why Google or anybody else have not made a map of Moon just like Googlemap of Earth. Are there some technical problems?
They did: https://www.google.com/moon/ Last time I used it, Google Earth provided a 3D view of the Moon and of Mars.

#38The image is 9000 x 9000 pixels. Future proofing for my own-it-someday 8K monitor background.
I tried opening the image, but it made my entire laptop unresponsive[1]. So let's hope the graphics manufacturers catch up with the pixel trent before those 8K monitors become mainstream. [1] On Chrome for MacOS. Granted my macbook is a couple years old, and the Apple graphics drivers are garbage.

#39Anyone have a mirror of the full-size lossless image? All the download links are dead atm.

#40This is great; as another pointer, http://clarkvision.com is my go-to source for beautiful astrophotography with technical explanations. Look for astro gallery and tutorials if interested
"The "articles" exhibit a litany of errors, nonsense and misunderstandings of how some basic algorithms and mathematical concepts work in image processing, including (but sadly not limited to) light pollution removal, deconvolution, the commutative property in mathematics, stacking, linearity vs non-linearity of data, basic physics and color theory.
After politely inquiring why he thought any of this was good practice or scientifically accurate and getting nowhere, even after demonstrating the mathematics and writing code to disprove some of his more fanciful claims and pointing out errors and untruths. The fact that I'm having to put this warning up, gives you an indication that that didn't go very well."
