Kaguya is a Japanese spacecraft that has been orbiting the Moon since October 2007. It is equipped with several detectors, but also – brilliantly, in my opinion – two HD cameras. The footage below is not a simulation: it’s real imagery of the Moon! Make sure you click the HD button, or go to the YouTube page to see this in full resolution.
This next footage is of the crater Antoniadi, and is stunning. Note the lens flares from sunlight entering the camera and reflecting inside.
I don’t know if the impact will be visible to small telescopes or not; I rather doubt it (though I’m sure it won’t be visible to the unaided eye!), but I’ll post more info as I find it.
