I like this idea. But i would think this type of tool/web is already used by more advanced users?
I did a quick google search and found https://welcome.astrobin.com/
I dont think this does what you specify but maybe the developer is capable of doing a thing like this?
Storage i guess is the running cost for a service like this.
But a tool to search for images that could be used to make a bigger FOV based on several images and also enhance images if you i.e need more "exposure" .
Implement this into zwo/seestar would also be a great tool even with a fee for storage.
