My guess is that people would really like to see it live. Sorta like how popular the "live stream of an eagle's nest" is vs. "a recording of an eagle's nest." There's just something about seeing it as it's happening, and being able to flip between different nebulas or galaxies or planets, with different types of telescopes and resolutions. I'm just speculating that I think such a service would be popular.

The stream wouldn’t be super impressive. You’d still need to stack and process the image. You can rent time on fancy internet connected telescopes. I don’t remember the name of the service I used, but you could request specific objects or places in the sky. I had a free trial for one and it was kind of cool, but I’d rather do my own pictures.

It definite wasn’t live. They just sent you the data when they were done but it helped me practice stacking and processing
