I think the Nikon Z8 is the best mirrorless camera for astrophotography and you can save $700 on this camera and lens bundle this Black Friday.

The Nikon Z9 is technically Nikon's flagship mirrorless camera. It's a much larger beast with better battery life and slightly longer video record times, but otherwise the Z8 is practically the same camera, in a smaller package and at a fraction of the cost, which for me makes it Nikon's best camera, as you can see in my in-depth Nikon Z8 review.
