Attached the D200 to a large telescope tonight. A Celestron 9,25" Schmidt-Cassegrain (2350mm focal length at f/10) which belongs to Sævar Helgi at www.stjornuskodun.is.
This is cropped a bit, but I could not fit the whole moon in the frame.
Used mirror lockup and a remote trigger, the telescope is F/10, I used iso 400 and 1/125 exposure.
