The big airless rock next door is the Moon, not quite as wide as North America with a surface composition much like the Earth’s mantle. Imaging the Moon is completely different from doing deep sky: its done with video! One shoots a minute or two of high frame-rate video and then software selects the clearest 10% or so of the frames to stack into a nice image. It’s surprisingly easy to do but hard to get excellent results.
I’ve included some star clusters here as well.
