The NIKON D90 body was mounted without ny lens and used to control the sutter speed and ISO, as focusing was done with the telescope knob (the weak part in the whole system).
Amazingly though, you could see the moon through the NIKON screen, even have video.
Mostly interesting thought was the video capabilities and result. You can see the moon moving at real time below:
What we really see at the video, is the moon moving with a speed of 1 Km / second, covering a distance of 60 km in almost one minute.
