FAQs:

Is this AI?

No, it’s a composite image made from a regular DSLR for the foreground and a specialized dedicated astronomy camera for the sky.

What is the red stuff in the sky?

This is the red light given off by hydrogen gas in space. Most normal cameras filter out this light, but I used a camera that is sensitive to this wavelength in this photo.
