From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

+1 from my side. I use Siril constantly to improve the signal-to-noise-ratio of my astro photos.
But I highly doubt that the photos OP described were shot in RAW and under the exact same conditions
I was thinking the same, smartphones would definitely do everything it can to make images sharp so it's probably not going to be easily stackable.
Still it feels like something should be there to combine the pictures to make better drawing, as there're softwares to generate 3D models from smartphone pictures.
OP still didn't describe in which aspect the images are bad.
Stacking (at least with astro software) only reduces noise, but even with stuff like focus stacking you can't turn a bad picture magically into a great one.
Especially since you need to plan that in advance and shoot under specific controlled conditions.
There's a reason why I always shoot in the shutter roll mode with my digital camera. When I have 5 pictures at once, there's always at least one that is sharp.
Playing safe is the number one rule of photography, hence why we always underexpose for example, since you can always rescue a too dark image, but if it's blown out white, you can't do anything.
Same with camera shake, focus, and so on. Even with all the AI shit and stuff, you just can't rescue some pictures.
I wrote a second comment in the section here with better instructions.
