All the download links are down at the moment. Here's a torrent link: magnet:?xt=urn:btih:j6ixrzpitvpmkx5tgroy6utcpqr5hhhj&dn=updated%20mosaic.png&xl=304863698&fc=1

There's a 4k wallpaper version. 213MB. Moon centered in the screen. magnet:?xt=urn:btih:6f64830246540020bf26b87b5c269088d563ac5d&dn=4K-mosaic.png

213 or 21.3? (link didn't find peers)

A 4k bitmap is still only 28mb.

Becausr the full-res version links went down often yesterday, I'm hosting it on my IPFS node, here's the link (for those on IPFS, if you can afford the bandwidth please pin it to spread the load :) ) https://ipfs.io/ipfs/QmVLTMHtLRhnft3QspDx4qTJeXY6hiib1j77UfQ... Also made it available in torrent form (with the IPFS URL as a web seed) http://www.urlhash.com/124410/mosaic.png.torrent

Earlier quoted context omitted.

Possibly the lack of adoption for native browser support.

Aside from the nontrivial security mechanisms that would be required to implement it safely, is there another reason why native browser support for torrenting doesn't exist yet?

I suspect it just doesn't look good from a PR perspective. who wants to be first to get slammed in the press for enabling piracy?

As an amateur astronomer who has looked directly at the moon through a telescope hundreds of times, this photo looks strange and artificial, though I know it's not. I pondered why this was for a bit, and came to the conclusion that its otherworldly quality is actually due to being superior to what one can see directly. At any one moment, direct observation will have artifacts of the air moving between you and the target object. This picture quashes all of that at once, lending an "uncanny valley" feeling I think spurred by the fact that my brain just isn't used to that level of fidelity looking at a real object. This work is fantastic.

For images of a moderate size such as this one, viewing it on a regular image viewer is less of a hassle.

Such as? I didn't see any example of that in the comment threads.

Firefox works great, as others have mentioned.

Windows Photos is having a hard time despite my strong specs. Any alternative to use aside from browsers?

I've tried most alternatives for Windows, and the best I've found is Nomacs[1]. It's very fast and customizable.

1.) https://nomacs.org

nomacs is a free, open source image viewer, which supports multiple platforms. You can use it for viewing all common image formats including RAW and psd images.

No no, it is strange and artificial. The stars are comped in from something else, and the moonglow looks like a gaussian blur. Still, it's pretty, and has hopefully inspired people to go stare at the moon.

To be fair, most astrophotography is "enhanced" one way or another - I can spend hours screwing around with a single DSO shot after stacking.

Here's a quick and dirty 30 second reconstruction using a shot of the moon from last summer, acquired in much the same way as OP - except using an EdgeHD 14 with an EOS 7D in video mode. It's pretty crap as last year was my first foray into planetary imaging - I usually do DSOs.

The 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.

My laptop is very much bog standard, but gimp had no problem loading it. Generally this may more come down to software implementation, rather than drivers

If you turn your apple retina display to 1080p mode, then I would think it's not that good when there's a 1:1 correspondence between physical pixels and pixel data. However when the size stays the same, I wouldn't expect much difference. A 32 inch 4k display downsampled to 1080p, well... :)

A down-sampled image has less noise than an image in its native resolution. You can experiment on your own monitors if you don't believe the theory, just remember to use font smoothing for non-native resolutions. You can also ask about it on the appropriate stack exchange, it is a frequent topic of confusion.

This is one of the advantages of shooting at a higher resolution than the intended target delivery resolution. When downscaling an image, the noise gets 'averaged' out of the image. For HD 1920x10280, a 2.7K resolution was a good choice before having to jump all the way to 4K. There's other technical reasons as well for shooting larger than intended use, but just re-enforcing the 'noise removal' process of downscaling an image.

If only we had something like imgur but the images were stored on bittorrent network.That would be great.
